    Hopefully before long HPTuners will release some 2.5 or 3 bar options for trucks.

    Yeah, I'm using TunerPro RT Beta on the Syclone and love it. It's great for OBD I with 3 bar and a WB. I just pinned the Wideband into the PCM and use an Ostrich emulator from Moates and do real time tuning while driving. It makes the changes in the emulator and if I like them I commit and then save to bin. I've got a chip burner and then burn the bin to the chip and put it back in the PCM. You can't beat real time tuning with a 3 bar. I haven't decided if I'm going to use EFI LIve or HPTuners on the new pcm for the L99. I'm going to use a few parts of the LS6 and then maybe stroke it and sell it's still in great shape except for 2 rod bearings. That'll be a while though. I might have to Turbo the 6.2 instead of Supercharge, money's a little tight so it's just a little playing at a time.
