a couple ?'s in one. looking for your input

[strokinbyeu]

i have a 2000 f250 4x4 with zf 6spd 230k mile. rite now i have a bully dog 6 pos flip chip. cold air intake. stock down pipe with 3.5 straght pipe no muffler

my 1st question is could i have an injector going bad?, when i start it in the morning it smokes white real bad and has what feels like a miss for about 5 minuts. if i set the idel up after a min it stops smoking alot after a min or two.

my 2nd question. if i need injectors i plan on upgrading to stage one's from full force, a t500 hpop from dp tuner and a dp tuner.
they are saying that the single squirt injectors help with mpg. i imagin thats only if i keep my foot out of it. is this true?
do you think that would be a fair setup?
would like to hear from some1 that is running the stage 1's

sorry if im rambling and i thank you for any input you may have

You might just need to replace the injector o-rings, but i will let the more knowledgeable answer.

The stage 1's should help mileage because of they have a more efficient design; however this may mainly apply to highway driing. Probably not as noticeable with in town driving.

If you plan to get injectors and dp chip, I would get it all from jody because there is no fee for the custom tunes you will need for the single shot stage 1 injectors.
The t500 is unnecessary unless you are having issues with your current hpop.

I've got almost the same exact issue. When I recently put my injectors in (Stage 1 singles from DP(FullForce) ) I also put all new glow plugs in. Very shortly after I had all kinds of smoke at startup and until I warmed it up it was really rough. Turns out half my new glow plugs were bad. I reused the UVCHs so I figured this also contributed to the problem. I replaced the bad glow plugs, and the UVCH on that side and now it starts much smoother and with MUCH less smoke. I still get a little, but it clears up very fast. Even when I forget or cannot plug the truck in the smoke doesn't stick around very long at all. I would start with your glow plugs first. Make sure they are all 100%. If they are, then you can start looking at the injectors.

On the injectors, going the DP route is about the best for Stage 1's. I do seem to get better mileage on the highway, but around town is the same. And, with all the extra power I can't keep my dang foot out of it! If you go with the single shots then an upgraded HPOP isn't necessary. I've had mine lightly modded by Joey at... Terminator? and while it helped but only slightly with the stock injectors, it shines with the singles. For the cost (~$100) Joey's rebuild would be worth it if yours needs new seals or anything. Plus, his mod also removes the check valves in the pump allowing both heads to see the same pressure, eliminating the need for the rear HPx crossover line. The only other mod I'd suggest is a FRx fuel cross over from RiffRaff to eliminate the need for the different #8 injector.

i just had the glowplugs checked out and a new selinoid put on. just replaced the cord for my block/oil heater.

the reason i was wanting the hpop is mine is original and i have had the one seal on the back replace about 5 times but it only last 4-5 months and starts to leak again. i thought if im gona be putting injectors in i mite as well replace/upgrade the hpop while i was in the area.

ill have to look into the fuel cross over you sugested.

again thank you for your input.

[INFRNL]

Honestly, your hpop is probably still fine, but I can understand your thinking. The T500 is definitely the way to go for most uses.

The Frx is a budget minded regulated fuel return system. It has 3 pressure settings via springs. It is good up to a certain degree. If you plan on just stage 1's its a good option. If you go bigger 238+, then you will want a different setup.

[strokinbyeu]

yea i dont plan on doing a ton of mods, i dont plan on pulling it. im the type that i cant go have fun with out having a really good shot at winning. i pulled garden tractors on a national level for 10 + years and still help build the motors for my dads tractors, we spent alot of money to do good and im just a cheap ass some times.

so im thinking just the stage 1 injectors, a t500 hpop and ajust on the fly tune from DP will keep me happy for some time.

another question i have is, someitmes i pull a skidloader. with the trailer it weighs in around 8k. if i have a towing tune for the 8-12k with the single shot injectors im not gona have to worry about way high egt's am I ? i know im gona have to watch the gauges, but if its gona be an issue ill go with the 12-15k tow tune to help keep it cooler. other than that its my nice truck to take out on the town and pull a 26ft 5th wheel camper 2-3 times a year.

if there is anything else that someone mite think would be a benefit to me please let me know thanks

[INFRNL]

Now that you have added some info, i have a slightly different opinion for advice.

Lets get to towing first. I have towed a mini excavator in a dump trailer; approx 15K without issue.
When you have a chip and tow, there is always a risk of high egt's. You will just have to keep an eye on them. For the most part you can to moderately with an 80 hp tune. For real heavy towing, I'd say a 40hp tow tune.

Now on to my new suggestion. Since you have a background of power, I am leaning towards you will want more later. Stage 1's can get you near 400hp IIRC which is plenty for many. You have forged rods and will most likely want more down the rd.
I would recommend getting bigger injectors and have them tuned back for now. this will leave you headroom for future expansion. later if you want more, you can get a different turbo and have your injectors retuned for full potenial or whatever you want. Bigger injectors are a little more now, but less in the long run if you decide stage 1's aren't enough.
I would recommend 250/200's, but some are going even bigger now. I think stage 1's are approx $1200 and 250/200's are $1895 approx. These can still run off a stock hpop or you can still get the t-500.

Just think about it before you make your final decision. This is basically what I did, mainly because I know I will always want more, but I am currently limited by pmr's. 250/200's and supporting mods will get you into the 600hp range. The 250/100's I have will get close to 550 range. No its not necessary, but as you know its fun. I can still tow without issue. Egt's can get up there, you just have to keep an eye on it. These injectors are less oil hungry than stocks and are more efficient like stage 1's. Being that you have a competition background, I think you will be happier with bigger injectors.

[strokinbyeu]

ok from what im understanding your sugesting i run what dp calles the Stage 3 Injectors-235-240cc with 7 hole nozzles at approx .0075. am i rite? will the t500 hpop will support these without any problem? if i go with these i wouldnt want wait to make the power but would probley have to go bigger than 4in on the exaust wouldnt i? my stock turbo wouldnt suport the fuel either would it?

[INFRNL]

I will have to check dp's site. I know they sell fullforce injectors and should only be either 238/100 or 200, or 250/100 or 200's
It would really be best to call them and talk to them. You will have to let them know that you want the injectors tuned back though.

A stock hpop will run these injectors, but yes the T-500 is more than enough. These are not hungry for oil like the stock injectors.

as far as fuel, I think as long as you can supply a steady 60-62psi, you will be fine. If on a budget, you can wun a walboro pump, approx $100. There are endless options when it comes to upgrades/mods.

[strokinbyeu]

ok thanks for your input, i really appreciate the information. do you know of any things i could read up on how everything is plumed. and just learn more about the 7.3 and what some of the ins and outs are. iv had this truck for 7 years and never really done much to it myself other than rebuild the zf trans, and a number of wheel bearings. but nothing under the hood except the cold air

[INFRNL]

Browse the sticky sections in each area on all the different powerstroke forums is a great way to learn. Or pick interesting threads to drop by. I just browse all the forums, its how I learn a lot.

Also if I am thinking about buying certain things, i call various venders and talk to them, ask questions, etc.

[strokinbyeu]

well thats a good idea !!! somethings need to be pointed out to me time to time, lol. again thanks for lettingme pick your brain and your time

[RIStroker2000]

i dont know why your telling this guy to buy big sticks and have them tuned down.. stage 1's are plenty.. and dont forget about turbo and expecially tranny upgrades .. noone really talks about the aftermath of more power.. to start.. tires, u joints, carrier bearing, tranny flush, rear leaf springs (they snap if there too rusted), ... front end..


all should be checked, because youll probably be doing some work on them even if they have been replaced

[INFRNL]

Everyone has their own opinions. You may think stage 1's are enough, but he may not. I only recommended the bigger sticks after he expressed his background a touch. A guy coming from performance/competition background is not going to be happy with stage 1's IMO. My suggestion will save him money in the long run, give him a feel for stage 1's now, with room to grow. I do not see anyone else trying to help him here. My suggestion is a good middle ground without having to spend a huge fortune. There are supporting mods for budget minded guys with 250/100's or 200's. 250's are right at the optimal price point for what you get and can do and only costs a touch more than stage 1's.

some of your reply contradicts you as well. stage 1's although not required do much better with a better turbo, just as the 250's I suggested. your stage 1's put a toll on the entire truck, just as much as the 250's. your tranny needs to be beefed up just as much as having 250's, its all the same but the 250's have headroom. If a guy want to drive like an idiot, a stock truck will not hold up either.

He is currently doing his homework and looking for opinions/suggestions. Thats exactly what i gave him. He is grown and is fully capable of making his own final decision. almost forgot, he has a manual I believe he just needs an upgraded clutch which looks like he may already have.
