[QUOTE="HPLouis, post: 16551592, member: 5445"] On 2 different Cobras, I had a 2.70, 2.76 and 2.93 pulley. The cars also had a JLT intake, mid pipe (1 car had a MRT catted H and the other car has a Magnaflow catted X) and 2.5 inch catback. The MAF was good with all 3 pulleys on both cars but I was hitting 95% and above on both cars on the injector and fuel pump duty cycles. The A/F ratio still held up to 6500 RPMs but the duty cycle worried me (tuner did say not to worry and shift at 6000 RPMs). Have your tuner datalog your car while dynotuning and you both can make a decision from there. [/QUOTE]
