So iv a bug STi and recently fitted a RCM trumpet induction kit. It hasnt been mapped in yet, but i spoke to the mapper (Aungus) and he said its fine to run the car with the kit it wont blow up just wont be optimised to run with that set up.
So i did a run on the motorway at the weekend and was doing some spirited overtaking in 6th gear (doing 120kmph never exceeding 120kmph) and when the car hit peak boost, it was fluttering like crazy and rapidly fluctuating between 1.3 and 1.4 bar on the boost guage.
Queation is should i be worried?
is this normal with the increased airflow?
Should i have left the kit off untill mapping time?
