Since when did the 94 and 95 Grand Ams have LT1s???
And just wondering...if you get your PCM tuned, doesn't that essentially do the same thing as the article decribes? It seems it's describing the new tune I have from Alex down to a science!
(only I can't switch to regular mode )
Trans Ams not Grand Ams. The pcm has two seperate shift tables built into it. We all know the regular. The performance shift would be the same as a mild tune. But it just holds the shifts longer. It does not make them firmer from what I remember. My truck has this feature. It is called tow and haul. But it works the same. I hit that button on my shift knob, and the fun begins. Alex can tune both tables. But he told me it is not in the Fleetwood, as that space is taken up by the traction control.
