I ordered a hypertech programmer for my 5spd 01 GT.
Apparently there are only 2 settings for advaning the timing:
87 octane or 93 Octane.
Well friggin Phoenix, AZ only has 91.
Am I screwed?
Guess I'll have to add octane booster every time.

I would proably just stick to the 83 octane program, but for those times when you want a little more you can add some of this to your tank...

Well is it becuase that the timing is advanced so that is the reason to run the higher octane? Try some 91 like quarter of a tank and see if it pings. If it does then you know that got to use 93. I think it should be ok.

That means I'll have to constantly reflash my computer.

Wonder if 91 will cut it?
Stupid Hypertech.

I bet that 91 will cut it, and anyway you've got nothing to lose since you already bought the programmer. I had a mixture of 87 and 93 in my tank when I installed the hypertech software and didn't hear any pinging so give it a shot.

Ok. Cool.
I guess I could also just keep a bottle of octane booster handy and just add it to the cheap 87 stuff.
right?

My buddy has a huge drum of Tolulene octane booster if you need some. Over at 19th Ave and Glendale.

I know several guys that tried to use the Hypertech with 91 octane and they ALL had pinging on warm days. Some had it all the time.

I was in Phoenix (Chandler) a couple of weeks ago and had the same problem. I couldn't find 93 anywhere, so I went to the track and 5 gallons of 101. Not cheap though
