Hi guys did all my n249 bypass and n112 today easy than what i thought it would be! but still my car is boosting to 12 psi for all of 1 sec then drooping to 8psi and it never did this until a month ago. it is not the maf and i cant find any boost leaks. but if i unplug maf it boosts to 12psi again. I should be getting a blanking plate of forge tomorrow so i can remove sai bypass. and hopefully fit my forge tip. but i still dont know why it`s not boosting. any help would be wicked thanks arron
