Yeah 60 mph is a bad spot for an M12 trans and 3.42 gear.... Its too fast to start in 2nd(hell 50 mph is too fast for 2nd) and way too low to start out in 3rd... All you can really do about it is start in 3rd and let it bog... Its really noticeable in a blower car that doesnt do **** until 4k....
Either need 40 mph in 2nd or 70 mph in 3rd.

Nice puppy punting OP! I'm like your 'stang buddy, don't mind losing to see what a clearly superior car can do to me (which gives me reasons to mod with a specific goal).

No track times yet. Pacific Raceways is hard to get to for me and my work schedule. When you do get there you never get more then a couple runs in. BUt planning on getting out once before the seasons done this year. Could tune to 92 oct now that i moved from Cali to Washington. But I had Charlie at RPM motors in Cali do the tune and love it. So I'm just safer now on better gas.
I am hoping to trap 130+ when I run for sure. Really want to get some 3.73-3.90 gears in this winter. with my tall tires and 7k limiter i can hit 162 in 4th kinda useless to me.
