When I purchased my 97 sport, I noticed that it had a JET CHIPS STAGE 2 PERFORMANCE POWER CONTROL MODULE installed. I never paid much attention to it until now. I did some research on it, and it boasts some performance increases, but also states that the use of 91 octane fuel is necessary. I've always used regular to fill up, and am now wondering if I've been doing any damage. I haven't had any issues to date, but just wondering if one lies ahead if I continue this practice. Also, what would be the harm in removing the chip?
Thanks in advance!
