built in 2 step

[Ptman22]

Has anyone tried the built in 2-step with a 15+ mustang?

I know they have LC but mine seems to not work right (or I don't know how to work it).

I haven't ive seen a few people use it but did not say what kind of success they had with it. I just don't like the idea of using it with the stock opg's and cs. factory launch control keeps it as a smooth steady rpm but ive heard it retards timing very aggressively during the launch. ive never tried it in my 54k miles of use on the car yet lol

I have had a two step on my car for years with hundreds of passes without a single issue. Stock long block. Shift at 8K as well.

I wouldn’t have your luck , I’d use it once and shatter my opg’s lol
