Thank you for creating this thread, I too am bouncing around with my locked ECU trying to make more power. I have recently had a jb4 added to my car too and I have all the bolts on's such as Catless DP from titan, HKS Super Turbo Muffler Exhaust system, AMS air intake, AMS charge pipe, and...
So my trunk doesn't open now too, I tried everything! I feel like the trunk opening button on the drivers door doesn't have that weighted click anymore too, feel like a more lighter click now. I hope I don't have to leave the car in the dealer for weeks.
Got the Ohlin street and track coilovers fitted the other day. The ride is a bit stiffer as I feel the occasional highway jiggle, but the steering feels more involved and she holds corners more predictably.
