My tuner said I could pick up about 5 to 7 Hp and torque on my car with a good meter. Could I get some suggestions for people with aftermarket MAF's. It does have to work with my fenderwell CAI kit. I was leaning towards Lightning meter and staying with my factory electrical module instead of the lightning module since it is calibrated for 42# injectors. I have all the bolt-on's like 70mm TB, CAI, PP plenum PI intake, headers, Xpipe and cat back exaust. I also have a XCAL2 tuner.
I'll let someone else take this one.
. Your stock meter is fine. You shouldnt have to change it until you go with some form of forced induction.
