Have any of you tried one of these? If so, did you see any increase in mileage as advertised? In the past I had good luck with Hypertech products and my PSDs.

 

I don't know that I've seen anyone post that has one of those on their trucks. Alot of guys are getting good results from Mike @ 5 star tuning (FTE Sponsor, screenname fordmdb). Contact him, he might know more about the HT products since I'm assuming they're a competitor of his. I can say from forum users experiences that have posted up that Mike's product is top notch. Check around in the V10 forum (which I deprive myself of now that ol' reliable is gone), lots of positive feedback there as well.

Yeah, not only is Mike the guy to go-to as sponsor of this, and the v10 forum, but he also had free shipping, and MONEY-BACK guarantee if you don't like it. The only thing you are out is the return shipping if you decide to return it.

 

I'd rather flush my $400 down the crapper. You will find that off the shelf tuners with canned tunes are basically a waste once you've ran a good custom tune.
