The turbo we have for his setup has an internal wastegate that is set to 7psi and obviously increasing boost you would use a Boost controller, but if you wanted to run lower boost ie. 4psi while were testing (fueling is the issue) how can you do that? with a boost controller also?
This is the main question that the net jus dont answer. i guess lowering boost isnt what people normally want to do. Plus the fact that a few of the turbo's come with a 11.3psi actuator which would prolly toastie the engine!!
Thanks guys :p
