JLT CAI/MBRP Race Catback/Lund 93 Tune on a 2015 PP1 6M

JLT CAI/MBRP Race Catback/Lund 93 Tune on a 2015 PP1 6M on new Indy 500 Firehawks. What do you think would be my best 1/4mile time assuming good launch and good shifts. I think stock the Gen 2 Coyote 6M car are high 12.8X? I think. Could these mods get me into the low 12.2X?

My buddy has a 17 pp car with just h pipe and roush mufflers. His best is 12.9 @ 108-109 mph at local hillbillie track 1500’ elevation. He runs mainly 13’s on street tire.

At my home track. In the fall you'd be close if you can launch the car. You'd be better off with a flex tune.

I hear ya. I drive 28 miles to get the stuff. I bought a 55 gallon plastic drum to store it in. So I wasn't always running for fuel in the summer.

Thats the advantage of a "flex-fuel" tune. You dont have to run E85. Travel the two hours and fill up some 5 gallon cans and keep it for track days ...the rest of the time you can run 93 or whatever is available ...the car will adjust.
