I went with the BoostMAX with the assumption it was safer for my vehicle and its warranty friendly, well I was wrong. I installed it step by step with the instructions provided and read them from top to bottom. The install wasn't that bad just took a little time. Then it was time to try it out. I went with the 93 octane setting because I put nothing but 93 octane in my vehicle. Set it to 75% like the instruction stated. Started off slow and then gave it some gas. Just after, my car started running very rough and wanted to die. Took my vehicle up to the dealer and my friend told me I lost compression in two of my cylinders. My vehicle has only 33k miles on it. So long story short, I get a new motor.
