Best Datalog program for '8746 ECU?

I'm new to the datalogging stuff, but I'd like to get started. I tried the TTS Datamaster site, but nothing for the computer I have. Has anyone used their programs successfully with the 746 TBI computer?
If not, what's the best bet for something user-friendly...beginner-friendly, I think is a better way to describe it. I'm not going to do my own chip burning (yeah, call me a wus), but I'd like to have information to help my tuner tweak the custom chip I already have.
So what do I have? It's a 350HO crate engine with a GMPP intake, a Holley 670 TBI, and a custom air filter box. SLP Headers with the AIR ports...tryin' to keep it at least legal looking. 3" CATCO cat with 3" piping to a single-outlet Flowmaster 60-series (I like to hear my tunes). GMPP 4L60 tranny (it's actually an "E" but had to bypass the wiring) and limited slip 3:23 gears. Suspension mods, too. I used it for autocross and track days until they shut our track down at the end of March.
Actually the car runs pretty well, I just think I'm leaving some power untapped and I'd like to run the datalogger as I put the car through its paces and send all that to my tuner.
Appreciate your comments, help, and suggestions

Thanks! But...

But where do I get that program? Like I said, I'm pretty new to this.

When you get done wasting your money with that idea, start reading the PROM Board. There's no way he can tune over the phone to adjust to your driving style.

Might even look at the threads mentioning EBL.

Thanks Grumpy. I honored that the grand master of EFI took time to answer my thread. I'm sure I'll be checking the PROM board out even more than usual once I get a chip that's even close to what the engine needs. The first data logging I did showed BLMs almost entirely across the chart at 108, so we're just getting started leaning out the fuel mix. For some reason every chip I've had so far from three different tuners has been super rich. I guess it's just to be safe, but I think the Vortec heads like a leaner mixture and maybe the Holley TBI really pushes the fuel. What's your experience with that?
