I have a 03 monte, the cat pluged up causing a misfire so i had a new pipe and a u bend delete installed witch took care of the mis. A few weeks later i installed free flowing mufflers, a fender wall intake now it seems like the car is lacking power. Im not sure if i need more back pressure or what. Any ideas??

Backpressure wouldn't be the culprit here, I believe a stage 1 pcm will help you out. Your engine is flowing more air now and may be running a little on the lean side without any pcm tuning. An upgraded pcm will do the trick

ok i was kinda thinking that, what options should i get?, ive been looking at zzperformance and intense, not sure if one is better than the other. also i have gtp injectors would it be worth buying the adapters and installing them? thanks

My opinion is get yourself a standard intense pcm: INTENSE-Racing.com: INTENSE™ Reprogrammed 3800 Powertrain Control Module (PCM) . It won't be too aggressive where you'll risk hurting your motor/trans but on the same note if you choose to start upgrading other performance parts, you can go through them and get it upgraded.
