I have heard only good things about tuning and so forth. I would like to hear any negative effects that a cob access port could have on your vehicle in the long or short term. Any input? Personal experiences etc?
The only real negative to it is that you would benefit more from a pro-tune for less money. So to some it's just stupid to buy an AP, but I got a great deal on one slightly used on the forums and I absolutely love it.
You'll also see a slight dent in your bank account from it too.
Negative effect on your bank account, some 09+ owners have reported knock, looking at learning view.. It isnt that great of a tune for 595.. Granted you get two generic tunes, however you can purchase a tactrix cable for 180, and buy a stage 1/2 package for 140.. the stage 1/2 package usually comes with support to custom tailer the tunes to your vehicle specifically.
