I second DrLoch's comment about our member named "2005HHRauto"... if you haven't already done it, look up every post he has provided regarding those tunes (link was included above) - even if you DON'T have E85 available in your area, he will provide SO much excellent, relevant and competent information that you will save countless hours head/heart ache.

If you want the most power available and want it to be EASY and still DEPENDABLE, it sure seems that he has the formula down pat. Especially if you have E85 available.

This site is PRICELESS because of the folks who have written above - congratulations for finding it!

Best of luck to you - keep us updated, too!

(BTW, it seems like you've already decided to NOT get a bigger turbocharger - excellent choice! After a little more research in these forums, you'll realize quickly that a bigger turbo is a waste when you have so much power available through simpler and cheaper methods)
