im emailing apr berlin to see what programs they put on the ecu. would the coils be causing the boost cut out and engine lights? its running about the same as it did before the tune.
yes, you should have changed coils before you did any of this next upgrade. never mod when your car has existing problems is my stance.
bad coils make it fall on its face under heavy load. feels like a backfire. and makes the CEL flash sometimes as its happening.
