I see you're new to this. Can't control timing or fuel, so absolutely not. Also it will give you whatever boost the stock DME thinks is safe, so you can put 25psi across the Rev range and it will ***never ever*** give you that. We're talking locked cars with no BEF because what kind of idiot would use a JB4 with an unlocked ECU?You can adjust boost pressure with JB4 across the powerband. You can easily add 100hp. Probably more. The engine might not survive, but you can definitely keep cranking the boost still she blows.
