2 step

Has anyone used here? Im getting ready to put a powerglide with a trans brake in a camaro. Since I cant find a 2 step for a ls1 I figured I would just use the one in the tune. I know you can't sit on very long. But will it hurt to engauge it when the tree lights up and stay on it till the launch? I plan on tieing it into the trans brake.

anyone? i am going to try it in a few weeks when i get my car back...would like some info first

You don't want to use that type 2step in a boosted app. Get a used Harlan (I'm using it and really like it) or a Synergy 2step. Both are ignition cuts not fuel cuts.
