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?

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.
