Fine, what ever, Why do I even try to provide accurate information here,

I was confirming what you said , as you stated that you were not sure and could be wrong!

Sorry for posting here at all!

Dream4,

Don't go away mad. Your statement does confirm what I had said, it's that you didn't say you were confirming it, just repeating it.

Other parts of your posting included new information to bolster the argument and we look forward to your input.

So you will spend the same amount or more money for the same mpg because of the programming of the PCM. Now if you had the proper programmed PCM you might save a little at the pump depending on your type of driving.

If you had a boost gauge you could the tell approx. the difference, as the "lite" runs about 10 psi of boost stock and the GT HO approx. 14 psi, and it is about 8 to 10hp increase, or decrease for every pound of boost gained or lost.

You are right. I had a LT Turbo before getting GT. The gas mileage is exactly the same. The difference is I use premium with the
GT.
