Default Larger MAF for a LQ4?
I'm resourcing parts for my upcoming build.


Will I need the larger MAF (IIRC 85mm) from the Corvette?






Thanks

I just upgraded from my stock 78mm mass air flow to
a gm 85mm mass air. Car picked up 5rwhp and 10 pounds
of torque. The 78mm did run fine through.

I'm also reading that the 85mm is good for up to and around mid to high 400's but if you are going above 500 need to look at getting a LS7 MAF.
