Went to the track today and got in a few runs, because thats personally how I like to gauge the effectiveness of a mod VS the dyno. Only did three runs but every one was a consistent 12.1xxx. My previous best was a 12.35 on a drag radial only, so just E85 picked me up an extra 2 tenths as well as 3MPH in the quarter. Definitely one of the most cost effective mods ive done! If I can get the launch down with this 6 speed I think ill easily see an 11.9. My 60ft was a pretty mediocre 1.98 and it still ran pretty good. Special thanks to Tim who is very responsive in answering any of my questions, and tweaking the tune until it was perfect for my car. Will definitely do business with EFI Tuning in the Future.

Awesome, way to represent the M6 SS! I want to do E85 also in the spring. Added 3 MPH, holy crap. If E85 does that for me I will be trapping over 121 mph. It should makes 11s easier for me. You will get there wih a better launch.
Like you I am struggling a bit with my DRs, NT555Rs with 1.97 something 60' my best so far. On my 5th gen 1LE I have seen some mid 1.7s on 305x18 NT555Rs. I had a couple of 1.93s in '16 SS on the runflats. They seem to launch pretty good for an all street tire at least sometimes for me. Also my DRs are 305x20 and 1 inch higher than the rear runflats. Bad decision by me. I think the M6 would benefit from more gear.
