need help problem with my 02 z28 i have a 2002 z28 with an automatic trans . i have this weird problem when i floor it from 70 mph it somtimes wont accelerate . it feels like it is starving for fuel .i have it at the dealer so far they cleaned the fuel injectors and changed the cats but now they are saying they dont know what is wrong with it . can anyone give me some suggestions.
I would start with cleaning your MAF and
putting in a paper filter instead of the K&N.
No mention of MAF buggery other than the
potential for oily contamination. Might take
out the HPP3 programming too and see if
you end up better off. Getting a logger on it
would be the single best thing to do.

funny thing is i took off the hypertech and it did it much worse .when i had the hypertech tuning on it i wasnt using the power tuning(didnt want to advance the timing) because i use a lot of nitrous but i used it to adjust my shift points and turn the fans on early and to adjust the rev limiter.
do you think i may have a bad maf because of the oil from the k&n?

Verdad Gallardo You need to find a bud with ATAP or EFILive or your
year/model of HPTuners and do some road work. The
codes only get set when stuff is totally whacked,
performance can still suck with non-code-setting
level of problems. Nobody can diagnose you with the
little info you have, just guess. Try asking in your
state/local section below, if someone local has the
tools; help may be closer than you think.
