S/C MAF etc.

Couple questions for those who may know. Buddy of mine needs to know if you peg the voltage on the MAF does the motor go rich or lean? His setup is Eaton blower, 91mm MAF, with a 125 shot. Runs great without the juice, gets real poor on it.

He is probably not pegging the MAF, and Im gonna assume hes running a wet kit.

Usually nitrous owners install the pill combo the MFG recommends and never check the AF on a dyno. Usually a 'suggested' setup runs extremely rich and thats where the power, or lack thereof will be noticed.

Let us know what happens.

On the old GM stuff I play with that is mass air, when you peg the maf, you can go lean because if the engine no longer sees any more air coming in past the max readable amount, it can't add enough fuel to compensate. On those old, and I mean old, EFI computers (late 80s early 90s) you could fudge by adding fuel elsewhere in the tables, not related to MAF.
