Anyone have experience with electronic tuning on a 6.0L?

My '05 2500HD seems like a dog, I'd like to get some low end grunt out of it, but the factory presets the timing curves and torque management so mindless soccer moms don't squeal out of control and crash into a busload of nuns and orphans. I don't think a 315hp 3/4 ton truck should perform like a bread truck.

I've got a cold air intake and an aftermarket MAF, and now I'd like to do some hacking on the ECM, trying to decide which programmer to buy. I like the HP Tuners Suite, but what has anyone else had experience with?
'46CJ2A, '47CJ2A, '48CJ2A, '50M38, '52M38A1, '62CJ3B, '62CJ5, '65CJ5, (2) '66CJ5's, '67CJ5, '67CJ101 '69CJ5, '69J3000, '70CJ101, '74DJ5, '73CJ5, '74CJ5, '77CJ5, '78CJ5, '78CJ7, '78Waggy, '83CJ7 (2) '95YJ's, '97XJ...One of them runs, kinda.

I would like to do something with my '04 also. Would be nice to have two settings on it, which I think some of the programmers have that option.

Try calling Jessie at this place: http://www.wait4meperformance.com/

I have two friends that have had 5.3 ecms tuned by him and they were both impressed.

His website is no reflection of his work... It's kinda lame.
