I am having my heads ported they will be ready tomarrow the 5th. Thet are flowing 265 on the intake 218 on the exhaust. With a 2" dia. 3" long tube bolted to the header flange the exhaust jumped to 232. I also just installed a comp cam with these specs 222/222 .563/.563 114 this is in an a4 car with flp long tubes orps with a 2800 stall. Questions are what kind of gain am I looking at? Am I going to have to get the ecm reprogramed or just need to dill the throttle plate? Thanks Rich P.S. I also installed comp.918's

I am not sure but drill out the throttle plate and see if it throws any codes.I would get it reprogrammed myself.

Some folks dyno like 290-300rwhp with stock motor and then 370-400rwhp with heads, cam and headers.

I think you will need to open up the idle hole a bit regardless.
