I have an APR 5.0 chip and I run it with a boost controller. I set the boost to 1 bar and sometimes when i go full throttle it would go all the way up to 1 bar and drops to .5 bar and stay there. But after I wait a little and go full throttle again it would hit 1 bar again. It happens very often. Sometimes even if i wait awhile it wont go back to 1 bar and i constantly get only .5 bar of boost. What could be problem here? Could it be the boost controller or the wastegate? I am very certain that theres no boost leak or anything. And theres no CEL

Have you done a pressure test?

Limp mode. Why are you using a boost controller to get 1 bar?

Then it should be installed in parallel with the N75. Is that how you have it?
