Programers and Decisions, Decisions...

im interested in the same thing. I want to know wahts the best for the price for my 98. I want one that can pull codes too.

My brother has the hypertech power programmer. I used it to program his car and it's pretty easy to use and works pretty good as well. I've heard good things about the SCT system but I'm yet to hear any results with the Diabalo unit.

Turbo92PGT - what you want is a code scanner, not a programmer. The hypertech programmer, SCT programmer, and other units are used to download programs into your cars ECU, not pull codes. If you wish to have the ability to pull codes, you need a "scanner" that will display the codes in the computer. You can buy some basic ones for around 100 dollars. Go to your local autozone and ask them about purchasing one. They should be able to tell you more.

i got Hypertech Power Programer III in my 00 GT. it's awesome

I have the superchips microtuner. Nothing bad i can say about it. IT fixed my speedo. Has many other options also. Two settings , an 89 octane and a 93oct. nto sure about the power gain but i'm sure there is some. And you can put it back to completly stock if you want. And the best thing of all is it takes about five minutes litterally. I also believe you can read trouble codes.
