Power Upgrade for 2011 E-350

I just purchased a 2011 E-350XLT 12 passenger to haul the boat, dirt bikes etc. I have not had any luck finding aftermarket goodies to unlock any hidden performance from the 5.4L engine. I know this is not a "performance" vehicle so spare me the "you bought the wrong vehicle". Just looking to improve throttle response, gas mileage and unlock any horsepower that might be hiding under the hood. Thanks in advance for your knowledge and advice. Currently, I have only added the K&N drop in filter and plan on adding a Cat-back exhaust very soon.

Reprogram the computer or Dyno tune it.
there is no cheap magical way to do it.

You bought the wrong vehicle

. I tried the K&N filter and tracked fuel economy before and after. Noticed absolutely no change. Bunch of marketing hype, like Amsoil IMHO.

You can probably at least make it sound cool with some glass packs...

Over in the V10 Modular Motor forum there are probably hundreds of posts about Mike @ 5 Star Tuning----he can and does work wonders with the V10 PCM strategies.
