DAMN !!! Oh, well I guess I'll wait around to put on that intake then...Zed

 

naw its all good zed lol i will check everything out in the day light laters, kevin

 

The Since the year 2000, the truck injectors are basically the same. Just swapping the injector from your 2001 model to these wouldn't alter the tune nor would it really be beneficial for performance. Regardless, +25 means the PCM is adding 25% more fuel that its programmed to do. 25% is the maximum adjustment it can handle, so its likely you are even more lean 25%. I'd check the injector plugs and make usre all 8 are snugly plugged in.

Are you getting flashing SES lights and misfires?

 

I've seen '03's with 19lb injectors before. It also depends if the truck was setup for flex-fuel, these trucks usually have larger injectors.

make sure you don't have any air leaks, is the engine surging at all?

good luck,

allen

 

man i leave you and danail alone for a few days and look what you go and do.

 

Yeah, I was thinking that about the injectors but didn't know for sure. Try putting in the old ones and see what happens...Zed
