Each stage tune adds a few psi, but if you have the jb4, just get the stage 1, which should add 120hp/147tq, then use the jb4 to run a higher psi map if you decide to use race gas for a bit.
I havent heard many complain about it, but my jb4 is/was buggy as all hell with aggressive driving, putting me into map 4 valet mode because it was losing the battle of telling the cpu what to do, shutting the throttle based on air/fuel conditions to protect the car. Im interested to see how much it improves.
750hp and mid 10’s should be the goal.

Would it be possible to get to 1000HP and 9's? I see modified Coyote Mustang cars posting well over 1000 HP with super charger from 5.0 litre, should be able to do that with 4.4 litre V8 with enough boost. Considering legendary 2GZ 3.0 litre turbo 6 can do it.
