Got a Polarperformance chip in my 1993 wrx for 1 year now.So i got a Dawes Device from a member on here,he said that it was already set at 1.1 bar.So i fited on mine and now it hits 22 psi,i have ajusted it and it still is hitting 22 psi.The car is now miss fireing.Help please.

 

Any one,PLEASE.

 

how come you fitted the dawes device was it overboosting? the device would vary on every car even though he said it was already set to 1.1 best starting with the nut but upto the end & do a turn at a time & trying it, it will be fuel cut your seeing as that is about 18.2psi

 

Ok,i will try that.Cheers.

 

Got the boost down to 1.1 bar but car misfires and 3000 revs,why is that?

 

I have the same set up. Do you get a miss when running with the standard BCS. Miss fires are commonly caused by plugs or coil packs breaking down
