Engine/Transmission (1998.5 - 2002) New injection pump, not quite fueling right

[MKinner]

i just had an injection pump installed at the dealership under warranty. it seems to me that it had a bit more agressive fueling with my old pump. i have a code 0602. fuel pressure is good, around 10-12. it runs and drives good, just not quite the power i had before. APPS is about 3 months old. is it possible for the catcher program to have been changed or corrupted? anyone else ever have this code? any thoughts would be HIGHLY appreciated. #ad

602 is a fueling calibration error code... I think..... all 2nd gen smarty's set it b/c they can't seem to resolve it btw the computers. I would assume that a catcher would set the same code.

Yes the catcher could have been changed, they automatically scan and possibly erase data when you take it in. That is why all computers must be stock or returned to stock before going to a dealer. Your programming very well could have been tampered with or erased.

If the ecm had an update from Chrysler then the tech might have updated it not knowing that he was erasing the catcher. BTW how does that turbo work with the mach 4s and catcher? I'm looking for a turbo for my combo. Not trying to hijack

yeah I do, the highest that I set the comp is 3x5 and only for short bursts. I usually leave it on 1x5.

so far i have been very happy with this turbo. for daily driving, i'm glad that i went with the 12 housing. quick spool up and i can reach about 40-42 psi. i am very happy with it.
