Hey guys I've got a 30det r33 with a Nistune Ecu, when I Got the car the guy told me he had it on the dyno running 20psi and the clutch coulee the handle it so they backed it down to 10psi. I've changed the clutch and flywheel now I want to run 20 psi again how do I go about tuning my Nistune to make it run 20psi I can't take it to a shop because there's no one in my shit little town that knows how to tune it and I can't afford to take it anywhere like Christchurch or timaru, any help is much appreciated
