I paid $550 for a tune on a modified LS1. The tune that was downloaded when they removed the VATS was junk. Night and day after the tune. Tuners can set the speedometer while the vehicle is on the rollers. It was a blast getting it done. With 3.73 gears my truck indicated 130 mph at 6000 rpm in 3rd. (Direct drive 3rd gear).

If your LS1 is all stock a tune may not be required. Cam and headers? It will work better with one, maybe a lot better. When they tune the motor they typically change the Transmission Full Throttle shift points a the same time. Short shifting a motor with a aftermarket camshaft is pointless. A incorrect ratio in the computer will offset everything in a bad way. My truck is 354HP at the wheels. With a LS6 intake, BTR stage II truck camshaft and shorties.
