my car was running abit of boost when i first bought it seing hows i have no history with the car ie tuners receipts etc and the guy had no knowledge on it i have wound my bleed valve all the way back in making 14psi so probably was running 17-18psi but i dont want it to blow up or be on its fueling limits.

i have found the guy who is running the cold start valve as 5th injector and have pm,d him for abit more info.

Still a bit unsure on what the fuel pressure mod does for fueling throughout the rev trange and weather i should opt for this or 5th injector;-( any info much appricated
