Hi, im running Mines ecu, decat,big exhaust, 1.1bar restrictor ring, apexi air filter.

Having trouble with the boost getting to high.

in second gear it boost around 1.2 bar in 3nd and 4nd it goes up to 1.3-1.4bar, which is alitle to much for my jap turboes i think.

sometimes it stoppes at 1.2bar in 3nd gear also, so it seems unstabile.

What can i do with this??

I have the same problem....My car was reaching 1 bar, apart from induction kit there was no other mod at the time! :eek:

 

I'm now BPU and the 1.2 bar restrictor ring doesn't restrict it enough!

I'm gonna have a bigger restrictor ring made up.
