10r80 1st gear delete tune?

[Andy13186]

I have a whipple with ~750+ rwhp and I am wondering if I should use a 2nd gear leave tune, or what HP a 2nd gear leave tune would be beneficial at? On the street 1st and 2nd are useless and if its below like 70* 3rd is useless too even with DR's unless the surface is good quality. Just wondering if anyone has experimented with 2nd gear leave tunes and what HP you guys think a 2nd gear leave tune would be beneficial at with a 10r80? Are 2nd gear leaves hard on the torque converter?

Interested as well. I assume the clutches should be upgraded before 2nd gear leave. But I dunno. Trans is what I have left to upgrade.

Not sure this is helpful, but I set my tune up with "roll race mode", as they say. Basically, if you go to Sport mode, then use the paddles it will still make WOT upshifts at programmed rpm even without paddling up. In this mode, you can start in 2nd gear or 1st gear. Drive and Sport modes still work as normal, both starting in 1st. This allows 1st or 2nd gear starts without a tune change, and also allows better full-gear logging from a roll since it won't downshift (and apparently has some roll-race benefit as well).

It’s one of my favorite changes I’ve made to the car. And the shame of it is that it’s seriously just one switch to flip in the tune then enter the shift points you desire.
