Hey guys so I have a 2013 5.0 A6.what's the best setup to go with? lots of 5.0 owners say boss manifold, JLT intake, off road pipes, 3.73 gears, and tune so what other setup are out there that you guys like. I was also thinking LT headers maybe??
I'm sorry first time owning a mustang...what you mean by circle d converter???
Headers and Intake are sore spots when it come down to money = HP. You need a good auto tune and i have tried several and recommend Dougs from C&L. Also a o/r pipe. Gears are another sore spot as some love the higher gear as you will see some running 4.10's and others staying stock with convertor. If you want a CAI for the auto get the Airaid.
Get a tune and o/r first and then go from there. Plus if you are going to track it nothing is worth more than DR's.
