I don't understand how you're mad about having to pay for a tune.So far it has been reliable and the power is progressive. The stock power was like a miata, you could basically just floor it around every corner and be fine. With the tune you actually have to think about how to apply throttle and there's plenty of power to push out of corners. I flash by myself at home, and it's all pretty straight forward. I hate the fact you need an internet connection to flash and that you pay 600$+ for a can tune, but other tuning measures seem to be focused more on power and straight line stuff than response and safety.
Overall I'm pretty happy with it. I keep wanting to go is38 for more top end, but I'm also trying to keep the car a bit lower power for Time Trial purposes. IS38 essentially drops it into the same category as the GTI TCR race car, and that would just be no fun.
I keep thinking if going UNI stage 1+ because I like their own+ philosophy with reliability in mind not all out power. I like the accessport for all the data you can view at a moment's notice but even custom tunes on a Cobb device scare me. You see race reviews on the forums but always people with some form of problem in the specific Facebook groups.
