I just sent my computers up to Overkill in Canada. I paid $180 for the "send in special". I had to pay $40 to ship my computers to him and the $180 for tuning and return shipping. My car runs and shifts WAY better now. I had DOD turned off completely. He also turned off or turned down the stabilitrak system so I can burnout going around a corner now without the damn computer limiting the power and making the car bog out. This Overkill tune just woke my car up. It seems a little more powerful now. The trans shifts WAY better too. You can also rev it past 4000 RPM in park too unlike the stock tune. It just makes the whole driving experience of my car better. It was worth the $220 FOR SURE.Originally Posted by 91parkave
