Hey all. I still have not figured out how to put my truck add-ons in the sig, so please forgive me. I have a 97 F-250 auto with 4.10's, gutted ebpv, 4inch cat back, lost kitty, open intake, downpipe and Wildman 4 pos chip. I have been having trouble with high egts when pulling my 6000 lb 5'ver, and am wondering about boost numbers. On the heavy tow setting, I am seeing about 22 pounds boosts under 3/4 throttle, and was wondering what numbers I should be getting, and so is Wildman for getting my programming right. How much boost should I be seeing. Thanks fro the help and info again guys. Colin

Sounds about right. /ubbthreads/images/graemlins/grin.gif

I think 23-25 is about the most you will see out of stock injectors... I made 28psi on mine but I had the larger CA split shots.

RyanPSD, I was thinking that in the low twenties was about all I would see, but I just was not sure, duw to my egt's getting high pretty quick with the chip installed. I guess I just fugured that I would not see my temps go that high so quick only pulling 6000lbs. I would hate to see my tempes if I moved up in load though!!!! Thanks for the reply. Does anyone else have anything different to add? Colin

Hay Colin, Are you getting any black smoke at WOT?
I would also check your fuel pressure while driving under a load to see if you maintaining 50+ psi of pressure.
If I remember right (it's been a while),with stock injectors I was hitting at least 25 lbs of boost.

I recently got a 6000# toy hauler tongue pull, and on the drive home I had to take it easy because the egt's were climbing fast. The main battle with trailers is the wind resistance no the weight. I installed the SD intercooler and it solved all my problems. I can maintain 65 through hills and only see about 1000 deg. pre turbo.

Hey Alaskan, I get huge amounts of black smoke at W/O, and it trails off as the boost catches up, but still has a decent amount. I am not sure what the H.P. ratings are on the different positions on the chip, but even on the second position which is probobly about 40 hp, I still get some black with the turbo spooled up. As far as fuel pressure, I have not checked it, and do not know how to. Maybe someone will chime in and tell me? Thanks for the experinces and info. Colin

It sounds like your fuel system is working ok so I'll have to agree with Wes_in_TX about getting an I/C. You can get one on e-bay for about 100 bucks and the tubing kit for around 400ish.

Alaskan, and Wes, I was affraid of that answer. I imagine that the innercooler is somewhat of an involved job. Taking off the front of my truck and all. Let's not forget cutting the hood latch and holes on the radiator bracket. I guess it is true, one power mod makes room for the next. I will watch e-bay and then eat my Wheaties!!! Thanks guys for your helpfull posts. Colin
