New Tune ahead; worth it?
I'll do a Weiand Street Warrior swap if its good over the LS6 in april.
I talked a bit to TTPerformance and I would go with em since I'll be in NJ in June. Looks like a great shop.
SO, is it worth it and what gain should I expect with the tune?
*this MD mustang dyno is 20-21% off, and is 500rpm off(see the sheet)*
