TDC Tuning sell the AP with the Cobb maps plus Jon adds his own base map which yeilds more torque and horsepower. He adds his base maps at no extra cost. Last I checked he was selling the AP's for $50 less than Cobb.

Jon offers two packages of protunes.

1) $150 fee - if you cannot wait for his quarterly visits to Tampa you can go with an E-Tune. You will need a laptop for this.. He sends you software, provides instructions on what he needs for data logging and what type of runs you need to make in each gear - email him the results. He uses the data logging and creates a 93 oct map and racemap (100 oct) map. Increased torque and horsepower are proven results.

2) $350 - protuned with Jon spending over two hours on your car, tweaks and makes certain customer is satisfied with the results.

He also believes in service after the sale!
