When I first got my Diablo chip the thing would shift at wide open throttle and lose boost. So I sent my chip to Willie Figueroa from Diablosport and he reprogramed it and it has never done it since no boost bypass or anything just wondering if this was weird. By the way Willie is the guy who drives all of those true street mustangs (7's). Anyway anybody else with this solution.

Thanks

It happen to me in my Harley truck. Got fixed after reprogram for 6# pulley. Very annoying.
