Upping The Boost On R34 Gtt

[Leeman]

You can use a apexi boost control kit that goes with the powerfc. Or you can just run a seperate boost controll unit. The boost controll kit with the powerfc is a little extra but if you havnt bought a controller yet id go with that and get it at the same time you can buy it with the group buy aswell.

can i just get away with using my profec b controller and not the power fc? what are the main advantages for using pfc compared to not using it. im only putting boost up to 11 or 12psi?

advantages is you wont have the restrictions of the factory ecu and it can the powerfc tuned will make the most out of all the modifications giving the car not just more peak power but making the power throughout the rev range that much better aswell.

You're better off getting a proper ECU solution, the stock ECU drops timing between 10-15 degrees once it detects boost creeping over 12psi.

I would definately get a pfc before a boost controller, you will get better gains out of just a computer than just boost, as the R&R is so savage on these. Having said that save up and get both, for that sort of boost level, you dont need any fancy electronic boost controller, a bleeder will work almost as well, and save you some money on the dyno and fitting as well. If your hands on, you could build a Jaycar IEBC, which is probably one of the best boost controllers aound, and it s $140 with controller.
