Running lean under boost at high speeds
Whenever I'm going 50+ mph and I hit boost (About 3500 RPM) I run lean (Popping in exhaust and stuttering/hesitation). Flooring it from 0-40 mph and it pulls great/no problems. I'm still under power train warranty so it'll be the dealership's problem but I'm curious what you guys think it might be. I've only tried cleaning the MAF sensor since that's cheap but that didn't fix it. I have a BNR tune but it has this issue on the stock tune as well.

With all you've clearly invested it would have been much better to go the HP tuners route, at least you would be able to actually post something to look at. I think that advise was given some time back iirc.

noted at least 3 issues on your graphs and returned mark ups. I am wondering if your car had a tune in it before. Are you absolutely sure? I am just asking b/c you said it misfired when you reverted back to the "Original" pull down. I am not about bashing b/c the bnr guy might have kept things in place thinking it was there from before and was working. But- that is a problem with remote tuning, it should have been cleaned up and given a new baseline. But, you have issues that are not hard to fix but it needs a redo.
