Boost leak? Does it idle ok? Do you have a vacuum gauge? Are you talking about air fuel ratio? Do you have instagram?

*brndck* · 03-24-2016, 12:56 PM

wtf? 50% of what? how are you determining this value?

mattgreen38 · 03-24-2016, 02:22 PM

it idles fine was doing some tuning on the dyno and can only get 50% air to the motor, like the exaust timing is off

Kingtal0n · 03-24-2016, 03:40 PM

what maf sensor and how much power

a z32 maf on a stock sr20det is only going to hit 50%~ capacity of the maf, but the voltage curve is parabolic so you can't go by voltage.

I'm not running maf I'm running 4 bar map through megasquirt
First dyno session I hit 430 rwhp
