Icon1 JB4 User Adjustment Help and Overboost Issues - 01-17-2021, 05:56 PM

Hello everyone.

I've got a 2018 Stinger GT2 with K&N intakes, Borla catback, Ultimate performance Intercooler + Charge Pipe, HKS sparkplugs (they were pre-gapped, not so sure they were close enough, all were a bit larger than .025"), and my most recent addition: Ultimate Performance Primary and Secondary down ***** With the addition of these came the issue of over boosting, so naturally I bought a JB4 along with EWG wires.

The JB4 helped tremendously with the overboost issue, however I'm still running into timing deviations, boost deviations, and throttle close. (It should be stated that I only run Shell or Chevron 93 oct and running V20 firmware) My question is where do I start adjusting to fix these issues? Should I start with lowering wastegate adaptation? And what is duty bias and should I adjust that? Just need some general help with user adjustment. Thanks. I'll attach a few logs incase that helps anyone.

You boost on both banks look fine, timing looks fine, and throttle closing is during auto shifts over 6k, all normal behavior. If you want to keep the throttle from closing, paddle shift before 6k.
I assure you this is a normal log.
