[The Fixer]

Prevost is the man, even for a mild motor. My car picked up a crapload of power over my stock chip with Jon's tune. I wouldn't spend the coin for a Hypertech when Jon is just as reasonable (maybe even better, pricewise) and he'll be in the car with you to do it. The off-the-shelf calibrations from those companies are better than stock, but nothing like having one burnt for your particular car and combo.
