i used to be able to hit 32-35psi with no prob. to day i felt like the truck did not have the grunt it usually does so i put it to the floor and could only hit 25 psi and it just felt like the fuel just wasnt there... how many mile do you guys go before changing your fuel filter? could this be a injector taking a dump? i plan on checking boost elbows and such tomorrow but i dont think i could hit 25 if i had a leaking elbow... or am i wrong on that to.

thanks in advance guys. its my everyday grinder so i would like to catch a small thing before it gets big.

 

It could be fuel. But my bet is there is a boost leak somewhere. Maybe a boot blew off partially. Try pressurizing the system to check.

 

boost leak...........check all the boot clamps

 

yeo boost leak,i hit 27 with leaking boots

 

Yep. Check all of your clamps. Take an extra hard look at the lower boot on the right side. It's just close enough to part of the core support to get a small hole in it.

 

Thanks guys! I just need to find work on it early because here in San antonio we are hitting high 90's

 

ok man now that just makes me mad i live in southern Indiana and if it was in the high 90s i would be loving it. i would be on the lake. it is lke 50* here for the high.

 

add crazy humidity in to it and it feel like its in the 100's

 

when you lay into the throttle does it pour out black smoke?

 

no. its still runs clean...ish hard full throttle in fourth and smoke pours. i changed the fuel filter and air filter and have had no problems
