I've got a problem on my cav turbo, thats driving me nuts. I've got superchips installed and it runs fine until I hit 11PSI, then the ecu light comes on and it limits boost to 4psi. I take my foot off the throttle and put it back on the ecu light goes off and I get boost again, until it hits 11 psi and I'm back to 4psi again. I've tried taking the superchips out and putting the standard chips back in and it won't start on the standard ones. I put the superchips in and away we go. The ECU light fault code is saying it's overboosting and limiting the boost back to 4psi as a fail safe.
Any ideas???? Please.
