Well I'm in the proces of trouble shooting an issue I'm having with the programer. After loading the programmer to my SUV I have been having issues at low RPM's. Sounds like the engine bogs down or the timing is off. Currently trying different things but may have to send back if I cannot resolve the issue. I have a Cold Air Intake and exhaust work done along with the programmer. Hypertech rep recommended that I add a fuel Octane booster. I added the best one they had at the auto store but this did not fix my issue. If I smash on the gas it's all good and can feel the increased HP. Hypertech stated that I may have to use the Regular gas setting instead of the Premium gas setting and still run Premium fuel however I will not get the full benefit of the programer.
