Does anybody know what brands are reliable for an engine tuner for a 2009 ford f150 lariat 5.4 liter engine?

 

In my 08' 250 I am running the 5.4 with the Bully Dog GT Platinum 40417 and they claim you can buy customized tunes from certain dealers. I am using the premium fuel tune right now and the throttle delay is gone and the response is a 100 times better. I havent noticed any increase in fuel mileage as of yet. I am actually still playing around with it and still figuring things out.

 

In the V10 forums there is a ton of good things to say about 5 Star tunings----give them a look-see first maybe.
