New tune for 2lb lower combo?

[yelostang]

I just ordered a 2lb lower and I was wondering if I need a new tune to run it? My mods are in my sig and I have a new heat exchanger on the way too.

I would say yes to be on the safe side...but im no guru or anything so i may be wrong.

You should definately get a tune. You should also upgrade your MAF and possibly your fuel pumps with a BAP or new pumps. You might be o.k. but I'm running the same exact combo as you and I'm starving for fuel.

Definitely will need a retune and like 7168548 said, look into picking up an upgraded MAF and BAP. Maybe even larger injectors too.
