I just purchased the HYP-370202 power programmer III off of Ebay Motors. (have not rec'd it yet). Was further researching the programmer at Hypertech's website and just as I figured the dual fuel option (87 as opposed to 93 octane) is not offered on my model truck. What would happen if I used 87 octane with a tuned chip? Would this possibly damage the engine in any way? Would the performance suffer terribly if I was that cheap and saved a couple bucks using the lower rated ocatane?

My other question is, the rev limiter option is also not offered for my programmer/truck combo, how bad will this hamper my performance? I understand all the other tuning features I will benefit from but can I reach my trucks new top speed even if a rev limiter may still be intact?

HPP III 1997

hey, I owned a 370202 of 1997 before and I think I had not problem with that. First, the rev limiter is not exist in the 1997 model, if I am not wrong. You can either rev the engine until 6000, At least I can remember with mine. Second, you can choose the premium gasoline selection or the 87 selection. I prefer use the 93 selection. It will work better. Actually, I own a 2001 GMC with Hypertech III #30008 and it works great with no problem, it is almost the same as the 1997 but has added 2 additional questions in the computer. That is it.

Need some help, can e-mail me at [email protected]
