'93 1500 Suburban with a Hyperthech Chip, what can I expect?
I recently purchased a '93 Suburban 1500, 5.7, Auto, 4x4. I am contemplating installing a Hypertech chip. Hypertech offers two chips. One chip is the Street Runner Power and the other is ThermoMaster. Can I expect any mileage improvement with either of these chips?
