Adam- What were the differences? I didn't see the dyno. Doesn't Gary have the twin turbo? According to Turbowerks they went from a twin to a single turbo setup for the 2.7 liter. He told me they are doing their initial installs on the 2.7 this month. I spoke to him via email and was going to have it done but the logistics of getting it to Austin along with a vacation conflict were a little too much. I had second thoughts as well as I was told this kit would be out "next month" on more than one occasion last year. Also, he told me that the ECU would need extensive reprogramming and I am kind of iffy about that. I am sure the kit is fine but I don't think I want to be the first one to put a turbo on a 11.3:1 compression engine. I would feel a lot safer if the compression was lowered. Maybe that's why the dyno is the way it is. I don't think you can load a lot of boost with that much compression. $ for $ I think a 3.4 swap would have been better. I know turbo technology has moved forward wuite a bit but Turbowerks claim that of the single turbo performing as good or better than the twin didn't make a whole lot of sense to me.
