ADJUSTMENT
1. Actuator
If the turbocharger unit which you select has the adjustable turn-buckle actuator, please use precise boost gauge and assure to fasten the nuts of the turn-buckle function when adjust it.2. Boost pressure control
To control boost pressure, aftermarket boost controller is necessary separately.In case of racing use:
If actual boost pressure will be increased much enough, although using boost controller, it caused by exhaust gas flow volume is exceeding wastegate capacity, and must keep back pressure with using smaller size exhaust pipes or must prepare additional wastegate function to fix it.
3. Engine control parameters
If the car is recommended to use regular gasoline originally, please feed premium gasoline when adjust ignition timing and so on to avoid engine blow caused by knock.NOTE
