Performance before and after tune?

Just wanted to know how much gain everyone picked up after getting a tune. Lookin for all motor numbers, preferably 4.8's, and which tune you used and the price you paid?!

Added Whipple w/stock Whipple programmer = 319rwhp/327rwtq on a 5.3
Custom tuned at DEZ Racing = 346/358 (fuel economy went up 1.1 mpg too)

On a 4.8 with the hypertech you will see around 11hp and around 8 lbs of torque with a 93 tune right after the tune has been installed may be a little more after a relearn period.

I gained almost 30hp from my Nelson tune I believe it would 500 for your truck definately worth the money and gained about 1.5mpg when I could keep my foot out of it.
