48 more HP?

[Shaners]

I got an email from performance products today that says the Hypertech Programmer III will add 48 more HP to my 6.0L.  If that is true, I think that is an impressive number.  Does anyone with the 6.0L in this forum use the Hypertech?  Could you tell the difference with the reprogramming? (I'd think you be able to feel 48 HP).  I don't like the idea of running "Premium" fuel, but I do like the sounds of the extra HP.  Hmmm...  348 HP from 365 Cubes

I'd like to know that as well!

Well, I've bought Hypertech stuff for my truck, and I think they dyno most, if not all of their products.

48 hp sounds like bs to me.

 

I own 3 Power programmers and although they do help, I doubt the claim.

 

Will they guarrantee it?  don't think so.
