Superchips offers a complete line of hand-held tuners to cover most domestic cars and trucks. While they are famous for the incredible power gains (12% increase in HP on gas vehicles, up to 150HP increase on diesels), their engineers and calibrators design the products for drivability. No more downshifting on big hills, they tune throughout the powerband for consistent performance from 500 to 8,000 RPM.
