Hi Guys,

Just trying to troubleshoot a problem for a friend.

Over the weekend we installed a FMIC and Manual boost controller into his stagea and we tried it on 7psi with no problems, 8psi no problems but running it on 10psi, it would stutter or surge a little around 5krpm before pulling the rest of the way.

Please note we grounded the stock manual 2 stage boost control and left it plugged in.

We have already regapped the plugs which are now 0.75mm so it shouldnt be a spark issues as far as I am aware.

Car is very standard with the only mods being FMIC and boost control. Exhaust is all standard.

Any help is more than appreciated.

Cheers
