Hey guys,
I've got a 2015 wrx which is pretty much stock with an axleback muffler delete. I recently got an accessport and put on the stage 1 OTS tune. It's been a few days since. I started my car today and I noticed burbles and pops coming from my exhaust and the rpms shot up to around 3k and stayed there for a while before dropping back down. Gauges on the ap seem fine. Anyone know what's up?
