I will bet you a dollar Tasca can do anything he wants to do.....If they are building Supersnakes and blower cars, they can tune this guy up. Especially since they are factory authorized. http://www.businesswire.com/portal/...ng=en&beanID=202776713&viewID=news_view_popup
Not sure what a "tuner" is but Tasca took my stock 07 450 RWHP and tuned it to get 550 RWHP, and all with a factory warranty. Don't think I'd let someone else mess with the warranty on a 15K engine.
Tlea, Can I ask who you work with at the dealership? I would definitely bring my car there if they could work on it.
I believe Dennis Gomes is over their performance dept. IIRC he's the one who tunes their funny cars as well
