I still don't understand how yours runs 12.2 @ 113 and my buddies can only do 12.7 @ 110mph with mods. You must have some severe negative DA to play with or he just got a lemon.
Actually one of my 12.2 runs was in a +1200 DA but the other 12.2's I have run was in +500 DA's. I have noticed that DA isnt affecting the 392 as much. BUT AIR TEMPS DO!!!! If is nice and cold out and the DA is still high the car still loves it. Is your friends an Auto or manual?? The manuals are nowhere near as fast as the autos. As far as Mods, there isnt much you can do to the 392's since there is no tuning for them yet.
