How much boost are you building ?

This one was 4500 rpm making 12psi. When testing we set it at 4000 rpm and 25psi just to see what it would do and it made right at 25

4500 is going too low imho. 5200-5700 and some bigger turbo cars need a bit more. I tuned launch up to 20 and that was a show haha

Btw that's on oem ecu. I'm sure the parameters and control is much different on the pro efi.

Of course 4500 was too low, was just testing. The launch after that was 5000 at 15psi and it blew the tires off. At the track I ended up at 6500 15psi which was about perfect, spittle spin to save my stock drive train
