The way I understand it fuel injected cars cant meter the fuel for larger cams at normal idle rpm. All fuel injected cars that I have seen with cams have a higher engine idle speed. My advice is turn up your idle.

Ill tell ya what, though... I have never heard a "cammed-up" 4.6. I'd like to hear one sometime.

Wait, cant you program the cam characteristics into a chip to meter the air at idle?

Surely the cam information is in the computer somewhere. I mean, the car meters the stock cams at idle. so why shouldnt it be able to meter the air with a regrind when you enter the proper information into the computer?
