im getting about 60psi when the car is cold once it warms up the oil pressure drops to 10-12psi at idle the car also feels slower once it warms i can spin the tires just by flooring it in first gear when it is cold but once it warms up it feels like it lost 50-100hp what could be causing this

list of mods
bbk 58mm throttle body
edelbrock shorty headers
comp cams camshaft
comp cams rocker arms
moroso cold air intake
ported intake

also if i take the car over 4500-5000rpm i get a check engine light

Well if you get a check engine light every time you take it over 4500, then obviously something is not right. If you find out what code it is, that would give you a better idea.

there is a good deal of us who have the pressure drop thing, I get it bad on long trips, car just feels like ***. A mail order tune is probably your best bet moneywise but who knows if that would fix it, maybe it's your cam, what are the specs of your cam and rockers? Best bet is to get it scanned or invest in a scanner to see what actually is going on, hope things work out for ya.

Sounds like O2's and/or tuning. Scan for codes and use that as a starting point.

i wouldn't go to a MECHANIC because he's not going to know your car. Ask someone who specializes in f-bodies because while the basic principle of most cars is the same, each car/manufacture uses a different method for almost everything.

Do not change your oil viscosity. When people say you should run a different oil in different seasons/climates, do not listen to them. Whether it be a 20 degree winter or a 110 degree summer, the operating temperature of your engine will only vary by a small margin, and the manufacture knows this. The engine was built to run on 5w-30, so run 5w-30. It sounds to me like you're just getting excessive knock and need a tune, but i'm not in your car so i can't diagnose it properly. Good luck fixing it and let us know what the problem was.
