buy one of those Pro-M maf's and see what she does on the dyno. I'm going to try my luck with the stock sensor once i put the hellion kit on my car.
How much power are you putting down at 10-11 psi?
Don't wanna spend 400 on something that may not work, if there is a for sure work around.
Upper 600s if i could spin it to 7500 if would be low 700s.
