That sounds like a really good price. Anybody get their tune on a basically stock vehicle?

21STCENTURYMUSCLECAR

We do quite a few tunes on stock cars, as it never hurts for the car to run cooler, have a more accurate but leaner Air/Fuel Ratio and extra HORSEPOWER.

Let me know if you want to get on the schedule.

Best Regards,

Everybit worth $300 plus an entire day? 12 hour round trip and $100 to $150 in fuel. On a bone stock A-4.

99 torch red vette

When does this tune special end?
Also is this price good for a supercharged car?
