NO tune !!! stock A9P, timing set at 8* spout IN
PMAS did a great job on the maf. They calibrated it to my cold side and I have NOT had a single issue. it runs better with 42s and the pmas then it did N/A with 24s and a pro-m.
I have no bends with in 12in before or after the maf which I was told helped me a whole lot. I did plan on a tune but after driving/checking plugs ect I didnt see a reason.... I used a narrow band air/fuel gauge as well. It NOT a wideband but combined with reading the plugs it gives me a great idea of where Im at.
At the time I planed on a PMAS maf just to get the car to run good enough to get to a tuner then possibly switch to the SCT maf he suggested but it ran so damn good I left it alone..
