Ok so heres the deal. I want to get a pro tune from Iveytune sometime in the near future. Probably around May or June. However, I want to be ale to take off the tune if i need to go to the dealership for some reason. I dont know if im right or wrong but the Accessport seems like the only way that I can totally take of the tune if i needed to. I don't want the AP for any other reason but to take the map off. Is it really worth the $600? What should I do?!?!?!

 

You can revert back to stock with ECUFlash too.

 

If you have a lap top (who doesn't these days), you download ECUflash for free. You can buy the tactrix cable for about $185. You can then go to your favorite tuner and have him tune your car with ECUflash. Take a USB storage device with you and he will put the tuned rom and the stock rom on it. When you get home, transfer the roms to your hard drive and use the tactrix cable to flash your car from tuned to stock whenever you need to.
