Think youve got it wrong the boost controller does up the boost to whatever you want!! Or I'm misunderstanding the Q?

Update!

 

I got my exhaust with full decat fitted over the weekend at Dudes and i was boosting just under 1.4 bar!! it was quite a cool afternoon so i suspect that the boost could rise..

 

so it looks like i need a restrictor ring afterall, for now i've just fitted the baffle to restrict it slightly.

 

We had some problems getting the fuel cut defender to work as it was causing the engine check light to illuminate, so it had to be disconnected.. i was suprised to find that the stock fuel cut was kicking in just under 1.4 bar. i thought stock fuel cut would be around 1.1 bar!!!

When I fitted my NurSpec I was hitting 1.5bar and no fuel cut.

 

I must be the first person to fit a restrictor ring before decat (next week :thumbs:)
