Hey I'm tuning a custom built twin turbo and a fresh built motor on a 2015 GT mustang and I am having issues getting the car to be ready to drive for break in/tuning. I started with my last PD blower as I thought it had a 3.5" intake (thinking it would be a good start) but I must have been mistaken. I Think my MAF vs Period is way off. Either way If someone could post us a MAF curve for a 3.5 intake. Any help would be appreciated.
start with stock MAF period and adjust fuel trims +/-
Use the stock 15 MAF period then multiply it by 7% should get you very close.
Thanks guys, I’ll give it a try.
Eeee he will be out of period using stock MAF scale with 3.5' pipe - im afraid that is not good advice.Quote:

Anyways if you want a good working base tune to begin with let me know. Not free tho.

The twin turbo part missed me, still what I posted will get the car running. Tweak from there.
Thank you guys. Had a total blank when building that base tune. Started right up and idled. Very much appreciated.
