wtf mate, car not running properly
hello everyone,
i have a 06 ss/sc with gm stage 2 airbox mod, magna flow muffer and torque dampener. and ngk one step colder plugs gapped at .38.
when ever i run the car hard, full throttle it runs fine, but ill stop at a light or something. ill take off and my car will bogg, ill give it almost floor it and it will feel like i wont go any where till about 3 or 4 grand and then car will take off what seems like normal, but even in second and third gear, it seems like the car is really bogging before 4 grand
i have also had it one time. it seemed like the supercharger wasnt working at all. the car was still boosting 15 psi but the car wasnt going anywhere and i was around 5 grand and just seemed like there was no power at all.
also i think this is normal for stage 2. ill boost 15psi and it will stay then start to climb till redline, when i shift i see about 17psi at redline in second gear.
the most recent things i have done. is put those spark plugs in, and it has done this before the spark plugs too. and i took out my left fog light so its like ram air in my intake, but i dont think that has anything to to with it
im trying to give you all the information that i have. and i think that is it.
does anybody have an idea whats going on. i have thrown any codes at all so its really hard to tell whats going on.

Misfiring somehow? Get a scanner to see, if you don't want to spend too much money get one of these http://www.davisnet.com/drive/produc...asp?pnum=08226 and you can post the results.

if i get this what will it monitor/tell me that will help me figure out whats wrong with my car, will it moniter my spark and my fuel? i just dont want to spend 120 bucks on something that i dont know if it will help with my problem
you think its the cat? i was kinda thinking that, but i did the old hit test and didnt hear anything rattling, could it be clogged? and wouldnt i throw a code if the cat is bad

Cats can go bad without giving codes. Do you have a check engine light? Do NOT buy that think gtpuser linked above, its worthless. If you have a code get it read from autozone for free. The reason I am thinking its your cat is because of the amount of boost your pushing on a stage 2 pulley, its pretty high. Try to do some general maintenance first, clean the throttle body, clean the maf, clean the air filter, change the plugs with ngk bkr7e's, change the fuel filter and all that crap. That stuff is really cheap and easy to do so even if it doesn't solve your problem its preventive maintenance. I still think it might be your cat though.
