chips, or programmers make hp and torque at low rpms? - Diesel Forum

johndeerefarmer · 03-13-2005, 11:42 AM

Do any of the chips, or programmers make hp and torque at low rpms? I am not into hotrodding, just looking for a little more hp for getting the truck started moving and a little better mpg. Most of the hp/ torque curves that I can find don't show any gains until around 3500 rpm.
For my driving and towing, I am never at those high of rpms.

Do any aftermarket products give gains at low rpms?

Thanks

I am wondering the same. I would like to hear some feedback on the new 1704-A superchips tuner for the 05's. I had a superchip tuner on my 7.3 and I was very happy with the low end, but the 7.3's have better low end stock than the 6.0"s. I have heard the Predator makes very good low end, but some people have experinced coolant puking with it. Let me know if you find anything out. Thanks,

Are you serious or is 3500 a typo? I've had 2 TS modules, 3 Quad modules, an Edge module, a Superchips tuner, a Dr. Performance module, and an SCT tuner. Everyone of them increased power long before 3500 RPMs.

I will say the modules did a better job of adding power sooner. Although the latest SCT custom tunes are supposed to be better than the base program I have.

with the exception of the neweer sct tunes the best bottom end module is the edge and flash tuner i give to the bully dog power pup...

Check out SP Diesel's new Eliminator for the 6.0 it really wakes up the bottom end of these trucks.

Is this a trick question? Look at the dyno charts!

johndeerefarmer · 03-14-2005, 09:55 PM

It's not a trick question. From the info that I can find on the Internet, the custom exhausts and air filters give their gains at high rpms. From the dyno charts that I can find, most chips and programmmers seem to give the best gains at about 2200 rpm and above. The dyno charts that do show rpms that low are showing very small gains (maybe 20hp or less).

I very seldom get above 2000 rpm for my "everyday" driving, therefore am not interested in paying big $$$$ for a box or programmer that doesn't make gains where I need it.

I want something to get the truck up and moving easier, and take less fuel doing it.....

I think that you may find quite a few conservative drivers like myself that would like a little more low end gain, a little better mpg, and a SAFE tune for our trucks.............

Hope that this better explains my question. [img]/ubbthreads/images/graemlins/wink.gif[/img]

You said "don't show any gains until around 3500 rpm" so that was the question. Down at 2000 RPM the torque gain would be less but most of the boxes do make additional torque down there. I'm sure Alvin @ Quadzilla and Dennis @ TS Performance can give you some information on the torque at 2000-2200. From what I'm told it is hard to measure torque down real low with an Auto Tranny cause of the propensity to keep shifting when you get on it down low.

I can't speak for all of the chips and tuners, but I know from my end, there is no doubt that I have loads of low end get up and go. The best way to put it is that when it was stock, I had to goose it a bit to get decent off the line acceleration. Now, I can get the same or better acceleration with just easing into the pedal. If I mash it good, I spin the tires. Couldn't do that stock. If you know anyone who has a chip, just go for a ride and you'll see.

The Eliminator we have just released boosts low end performance quite nicely. We tuned it to provide a nice boost all across the curve. the power increase will be evident right off idle.

johndeerefarmer · 03-15-2005, 03:33 PM

How about more info on your product. Cost, dealers, benefits, dyno curve etc? I have been checking your website for the past few weeks and it hasn't been updated.

Thanks

Same here wiating for more info.

This may answer some of your questions:

They do have a few distributors on this site as well, but I'm not sure which ones exactly.

johndeerefarmer · 03-15-2005, 07:54 PM

That helps. Thanks. I will see if the company replies with more info.

It looks promising. The economy mode interests me, as well as the ability to keep someone from stealing my truck.........

Of course, having extra power available if necessary, would be nice too.

We are burning the midnight oil to keep up with orders and get new stuff to market, so please don't think we're ignoring you because we certainly don't intend to. I will be posting a dyno chart soon enough, but we're rating the box as a 125HP box. The dyno chart proves that out pretty well, and more than one person has commented that it has more power than an Edge Juice, which is rated at 115 if I am not mistaken. I cannot discuss prices on the board, but there is a price listed on the website, under the eliminator section. If you are looking to buy thru a dealer, give me a call and I can point you to a few who are authorized to sell the new stuff.

Regards,
