I have fixed my boost leak, I think, but I am still experiencing a power problem. Truck is a STOCK 2003 S.O CR motor 250hp/47RE auto except for Airdog100 and homegrown CAI and a 5" exhaust. Truck has no get up and go especially at interstate speeds. When I press the accelerator at highway speeds it seems very slow to react, the truck will go faster but it is slow in getting there. I have checked my rail pressures last night while cruising at 65mph and they hovered right around 90mpa ( 13,000 psi if my math is correct). The truck idles at about 35-37mpa (5,000-5,350 psi) and at WOT it will hit 150mpa (21,750 psi). The outside air temp was 55° and my IAT temp was 70°. All of these numbers were taken with a diablo predator in the diagnostics area. (I am not running this programmer). There was also a reading for intake temp that read 150° and it never changed. I would really like to figure this out, I need that extra umph to pull my camper, and i swear all this started after i installed my airdog this past spring after the Holley blue electric one crapped out on me. I do not have EGT guages, or tran temp guages( YET). I do know that the truck is making about 22-23 pounds of boost with the turbo (HE341 I believe is the stocker). Diablo shows 15 psi at idle which i have to assume should be 0 and at WOT it will read 37-38 psi which should be about 22-23 pounds of boost by doing the math. The truck has 141,000 miles on it with 3.73 gears, it blows very little smoke and purrs like a kitten. The truck seems to run very well it just doesn't have the power I think it should especially on the interstate. I also plan on lashing the valves in the very near future!! Other information should be in my signature.
Any Ideas or thoughts on what the issue could be. I am sure i have forgotten some information but i can hopefully answer any further questions. One last thing the truck shows no codes with the key trick, the diablo or a code reader.
--- Update to the previous post...
Also the fuel filter was replaced not long ago as was the air filter. Fuel filter is a 2 micron filter and the air filter is an oem filter. Also are the boost numbers in range or are they short for that stock turbo??
