So I recently purchased a 2004 Neon SRT-4 with the Mopar stage 2 with toys upgrade. I took it to a dyno to see what it would do. I wasn't impressed!

My max power at high boost and my open cut off open was 216 HP!!!! And 268 Ft. Lbs. of torque. A stock SRT that was down there put down 228. My car was throwing 7 different codes. Would those have that much of an effect?

I got the codes cleared and it seems to run a lot better but I haven't had it back on the dyno yet. There is a P0038 code still which is the O2 sensor but I've been told that the stage 2 PCM will read for it or something but can't find one.

Can someone give me some information please?

First off, you've posted this in the wrong forum. This is the FAQ section. This would be more appropriate in the Off Topic -> Water Cooler forum.

As for your dyno, depending on what the codes actually were, they may or may not have affected performance. I would suggest you check for boost leaks. This is the most common problem with our cars. What PSI are you spiking/holding? I know that when I first bought my car I had a hose totally disconnected which gave me 0 boost at WOT. Fixing the boost issue cured all issues.
