Wanted to just intro myself. Been a 1 year owner of a used 15. I've carbon cleaned it and octane boosted it. It's probably running around 460-480 hp right now. Planning on more silent mods as I go. Spark plug change instantly changed the engine from a sluggish hard charger to a roaring ass that can't wait to go; Prompting me to schedule a drive train fluid swap.
Anyway. Has anyone noticed their front door speakers not operating in xm? I'm not sure if it's just me.
