Which gears for M6+paxton?

[brianjh20]

Im running out of gear at the track....
2012 Boss with 3.73s ran a best of 10.87 at 129mph shifting into 5th I hit the limiter a few hundred feet from the finish. Ran consistent 11.0s at 128 keeping the car in 4th.
I have 295/60/15 MT et streets
Should I go with 3.55 or 3.31s?
What are some of your setups?

I would go to 3.31'a if I was you. You will see the best results at the track and on long pulls you will pull forever.

Having that setup before a 3.73 is a good n/a gear but with fi it's just to short .. a 3.31 gear is about perfect for the street and track.

Another vote for 3.31s. With a 28" tire you can finish the quarter mile strong at the top of 4th at 130-135mph

Would 3.55 be better? Or still too short...
More fun on street and finish in 4th gear at a higher rpm?

I went 3.73 to 3.31 with paxton, no regrets.

I went down to 3.27's to stay in fourth through the traps but I'm sure 3.31's would be just fine.

Had 3.73, switches to 3.31's and it's perfect. 3.73 was useless, no traction.

I'm about to put 331s in my boss.
