More performance

[BOWTIE 3]

I've had my '01 Silverado ExCab, 5.3, 2WD since new. Have added air-intake mods and a cat-back exhaust. Now I think I'm ready for one of the PCM tunes. Westers has been around for a while with generally good experiences, but now this Wait4Me outfit has popped up, and for a lot less $! Has anyone had any experience with the Wait4Me PCM tune? Also is it best to supply them with my PCM or buy their's and keep mine as a back-up? And, do the tuner companies put the latest up-to-the-minute GM PCM updates in the unit they ship the customer?
