Hey everyone! Not sure if this is in the right section so apologies if it is.

I am wanting to know if I was to use a line lock and lingenfelter 2 step would it help build boost in place of a trans break and not cause the car to push through the front brakes. I'm wrapping up my build so I'm a little in the dark if this will work. The 2 step and line lock would be linked to the same button.

Turbo 5.3 on factory PCM
Th400 w/circle d stall set at 4400 specs for turbo

Any thoughts on if this would work or would it best to skip the 2 step and just run off the foot brake until I get a TB?
