You can set the boost at whatever you like with the controller. At that point the ecu isn't limiting boost it's controlling the fuel & timimg & all that. Personally I'd set it back to 10 before you get a tune. I'd also install the injectors so the tune is for them. I got a tune for dual pop, full exhaust, stillen intercoolers, & stock 370's. Literally the next weekend an injector crapped out so I got a set of 740's and had to get another tune.
