you need to tune the computer to pick up the higher air flow. however we did have a 402 that got 2 tenths faster after we put on a bigger granitelli one with same tune.

Honestly your better off taking it off and reinstalling the stock MAF. Seen several people have nothing but trouble. Plus it'll probally cost you over $100 to get it tuned correctly with that maf

It's very simple to re-calibrate your MAF table. It's done all of the time. Although, I don't think your programmer has the capability. Where are you located?

Go to the tunning section & start a thread requesting help w/ re-scaling your MAF table & note your general location. There's a good chance that a member will help. If not, a local tuner can do it for a nominal fee.

FYI, at Wide Open Throttle (WOT) The MAF calibration means nothing.

Most likely he is speaking about part throttle acceleration. In theroy, if it was a restriction the more air you can flow the more power the engine makes.

Agreed, because they must adjust their tuning to consider the MAF's aftermarket calibration.
