Just picked up an 18 gti m6 & wanna get a tune. I have APR stage 1+ on my 07 but I've heard they discontinued their stage 2 tunes across the board. I'm looking at unitronic & Cobb as it appears both offer the stage 2 tune. I like the unitronic option as I can flash the car myself. Cobb appears to offer the same but not that knowledgeable about their handheld access port. I would initially go w a stage 1+ as my car has a lot of warranty & need to be stealthy if it has a downpipe installed the dealer is gonna know. Any input is appreciated
