just a little update:
did my PA state inspection this AM.. absolutely No problems....and the car sounds amazing from the outside... The mechanic stopped and started it a few times (not sure if he was trying to throw a code vs liking the sound), there is def a "modded" sound to the set-up.
Interestingly, as I was driving thru traffic I had to make sure that the M button was not engaged... limp mode is waaay more responsive now (speaks to spool-up time).
However, i used to experience a noteable "jolt" when the M buttom is pressed while driving... Its still there... just less pronounced... Can anyone back this up??

ps. if there are any concerns about emissions testing, I simply let the car idle for 30 min before my appt (shop is less than 3 miles from my home) that way the primary cats are at temp (hence fully functional) at time of inspection.
