launch master issue

[06attakturbo]

Just a quick question about my msd launch master. It's very inconsistent works sometimes but not all the time more a less a 2 step when not working no boost building. This is wired through the brake lever the light comes on msd when brake is applied.Tried another box same thing. See lots of people like using the brake set up. But is a button the way to go to make it more consistent. This is on a front mount turbo apex tunnel dump exhaust.

Shouldn’t matter it just needs the signal to activate. How much boost do you build when it’s working? I have one and I’m curious. I don’t remember making a ton of boost either.

When it works 6 pounds when it doesn't not even 1 pound. Huge differece when drag racing on snow.

Probably because you have a big difference in intake air temp / exhaust temp and AFR's after being heat soaked... All play a big role in consistency with any 2 step anti-lag... If those variables aren't consistent, neither will your 2 step.
