    Not sure what your plans and goals are, but I have run the A9P with the T5 with no issues at all. Most rumors/internet lore states the A9P has more timing than the A9L, but I can't personally verify that. I didn't notice a huge difference between the two computers with my T5, but I honestly don't think I would go through the trouble to swap one for the other in most cases. Just my .02 good luck!

    I don't think you are going to find anyone willing to trade down unless you are willing to front some extra money in on the deal.

    Wouldn't the stock "tuning" timing charts on a quarterhorse from one to the other, show that?

    Quite possibly, but I have never owned nor used a quarterhorse, so I can't confirm.

    I agree with Trey. I didn't see any difference at all. Not worth the hassle to try and trade and put up some $$.
