Only "mod" I have is a better drop in filter and the intake box snorkel taken off (which I'll probably put back on).
Pretty happy so far. Only weird thing is that it doesn't seem the flash is allowing me to change the exhaust flap to open on demand.
No codes... yet. If I do get some I'll post them here. Also hoping overheating/boosting isn't an Issue. May reduce the boost as this is my daily driver.

I flashed Stage 1 93 around 3 months ago. No problems so far. Yeah, the flap settings are only open, close or auto.
