Community Q&A Question: 75mm big enough

Asking About: Mustang Pro-M 75mm Mass Air Meter For 24lb Injectors & Fenderwell Cold Air Kit (89-93) 5.0


75mm big enough

I have a C&L 80mm maf on my 1990 5.0 LX now and it's for 24LB injectors. I was told my car would run better with a Pro M. Looking to make the car run better. Idle hangs to long whenever you let of throttle. My mods are as follows

Trick Flow intake ported to heads
Edelbrock heads that have been ported and polished as far as they can for the street
E303 Cam
1.6 Roller rockers
stock throttle body and spacer as of now.
JBA Shorty headers
Magnaflow X and Cat back

A 75mm meter would be perfect for your set-up. You really do not need anything bigger. As far as the idling hanging up high, I would check your idle air control motor to make sure it is not sticking.
