I lucked out an was able to get the Stage 2 file the day before they discontinued it. I have still yet to talk the Minister of Finance into a new exhaust to be able to flash back to it.I wish I could've went with APR's Stage 2 ECU before they canceled it. Recently got their Stage 1 ECU/TCU and it's incredible. I plan to go K04 with a CTS K04. The question is, which lol. I know that their K04-X is the bees-knees atm. About to hit 130,000 miles FWIW.
The TCU is good? I've been wanting to do that too.
