M6 is a tough deal to get it to 60', a good driver can get a M6 to 60' @ 2 seconds flat. Without the good 60' time your final ET will suck. My best ET so far is 13.91 @ 111 mph 2.6 60' , left 6 10ths on the table. The best 60' to date is 2.3 but messed up the big end. Short shiffting is suppose to be important. By looking at Dyno sheet it starts to flaten out about 5700 rpm.
