02 7.3 Torque loss??

[crshelton21]

hey ive got an 02 f250 with 7.3. its 4x4. i bought it in february. since then ive put a 4'' to a 5'' tip exhaust as well as new glow plugs and an aftermarket CAI. since ive had the truck i used to be able to take off from a red light and almost rip the rubber off my tires and had amazing acceleration. the past 4 months its been a different story... ill stomp on it and it will take its sweet time to get on the down the road... now top end isnt bad.. once it gets to 55 itll accel a little faster... but its no where it was... whats goin on? i also have a predator tuner and i have usually left it on the 85hp performance setting. need some help.

have u checked for boost leaks? just sayin its the easiest solution.

[crshelton21]

how do you do that?

[captnflooradies]

if your beating on that truck with a chip and a stock tranny your slush box isnt gonna last look into getting a valve body..

[powerstrokin2000]

best way ive found to check for leaks, is to rig up a one way valve like on your tires on the intake tube and pressurize the system and look and listen for leaks. do a search for boost leak checker and you will find all kinds of things

When is the last time the fuel filter was changed? Might want to start there.

[crshelton21]

yep changed it out. it was nasty.. and noticed a little difference. but still is not the same. im beginning to think its a trans problem. its got 166000 on it. its just not shifting right. cant figure out why. need some help.

[crshelton21]

turns out i went to get the glow plugs changed and the guy that changed it forgot to plug a boost sensor back up.. therefore the turbo wasnt helping me out any. runs great now.
