i have been chasing a problem on my truck for a while now and it has cost me alot of money. i have noticed a difference in my truck for a while now and have replaced just about everything. my truck does not seem to have the same umff it use to have. my throttle does not have that load on it like it use to have. it does not pull hard like it use to. my boost numbers are lower(47 max with wastegate hose plugged). i use to be able to hit 58. its a combination of everything and it is driving me nuts. here is a list of stuff i have replaced: vp44, timbo apps, neighbors whole tps, map sensor, iat sensor, trans sensor, no boost leaks, 3 different injector sets, swapped out different chips(edge, adr., smarty, fms, no chip), new air filter, changed fass filters. dont know what else to do. i honestly hate driving my truck the way the throttle feels. my neighbor has a 99 and i will turn his chip off (he has 150 injectors) and his throttle feels like mine use to. at this point i dont mind the power thing but more of the load on the pedal feeling. infact, it is harder to drive my truck the way the throttle feels flimsy. my truck has only 84k miles. do i drive this thing off a cliff:mad:.
