Ha, I was once you.
Yes, bigger Maf--- new PI80MM definitely outflows the old bullitt 75. Then I had it calibrated for the 42's. Then came the PMS... I am still saving for the power pipe and mr.freeze. then to have it tuned.
welcome to the big spenders club.
Every article and person I talk to claims an honest 2lb increase from the AFM power pipe as it should with the premium price.
I did note that the upr doesn't have a 4inch intake for the bigger maf that you will need. it has a 3" rubber coupler. Hey what's 30 bucks for a coupler.
