Hey guys, Ok looking at tuning my car again, now I did have a Cobb AP for a bit on my car but at the time my car was having a few issues so i ditched it and now I regreat that,

So i am debating JB4 or another Cobb, the Cobb was easy to install worked well, but i also hear good things about JB4. With the JB4 the install scares me a little as i dont really wanna risk messing up anything in the ecu, as well as i dont have a labtop to data log with,

Whats your opinions? car is stock right now,
