Helped my buddy put the 87 performance tune on his 2012 ecoboost today. What an impressive improvement! Pulls very hard through the gears and I really love how the transmission shifts now. Can't wait to get my tuner ordered.

 

That's cool!

 

Will a tune have any effect on warranty? Thanks

 

Possibly.

 

Tunes are great on boosted vehicles.

 

Curious to hear what kind of MPG you get after the tune.

 

If you're worried about a tuner/programmer voiding your warranty, wait until the warranty has expired. If an issue arises on a warranty claim and it can even remotely be tied to the fact that a programmer was installed, you'll be out of luck.

Good to hear 5 star does a great job on EB too!
