What are you doing to them exacty? Timing, tranny tuning? I'm fixing a wrecked 07 STS V8 and I considered tuning it when it's done. I have HP tuners and there are about a thousand transmission tables :bonkers:. Since it's going to be for sale I don't think I'll spend the $100 on the credits.

I have several sets of GM calibrations. You can see the differences in them. I spot hot the hot tunes and then work on those as my base tunes.

Do you have a stock 07 STS tune I can read with HPt? I downloaded one from the HP tuner site but it's an export tune so it might be different than the US tune. My wrecked car doesn't have an ecu so I can't download that one.
