I recently swapped out my factory intake and exhaust, and I was wondering if I would benefit from a performance tuner? The new intake is a K&N 57 series and the exhaust is flowmaster. Thanks.

 

I just did the Airaid intake and a throttle body spacer and was wondering about the same thing. I have 2007 f-150 Super Crew with the 5.4 a 6" lift and 35" tires and 3.73 gears and i'm wondering what tuner to buy or what tuner you guys and gals have had work for you. Thanks for the help!

 

You will benefit more from a tuner than any other cheap bolt on. Make sure that you get one that has a CAI tune to allow for your K&N.

Longnlow, I'd recommend pulling off that TBS and selling it to contribute to your tuner fund.

 

Call power hungry performance and they can write a custom tune for your truck
