What's up HKPRO5! I just boosted my p5 a few months ago and checked everything you have now. I currently run the MSP and SSAFC and I swear it's plug in play with the super map that comes with it. It's really easy just to get an msp ECU instead of trying to tune the p5 ECU.
Not sure if anyone mentioned this to you, but if you want to run the BOV, yes you can recirculate, but you can also put the BOV about 6 inches before the MAF. So it's BOV -> MAF -> Throttle Body. Glad you're going turbo![]()
