Hey y'all. I was curious if anyone has any experience with the Hypertech tuning chips. I noticed that the chip is supposed to be used with high octane fuel (93 in my area), and was just wondering if doing that would have a big impact on my engine? My El Camino is an 86 with a 305 and q-jet carb. Just trying to pull some more power out of the engine, mainly torque, and I've read these help. But I'd like input from my fellow El Camino friends.
