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

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 get huge amounts of black smoke at W/O, and it trails off as the boost catches up, but still has a decent amount.

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.

Make a weekend of it and invite some of the other Colorado boys over for a BB-Q and wrench party.

P.S. save the beer until after the work is done /ubbthreads/images/graemlins/wink.gif.
