Well, I sent another follow-up message to Gary at Sprintex today to check the status of tune. He expects to see something in the next couple days. I hope so, because I finally got a quote from the LS installer. He came in about $10k more than Motech's price, so while I may still consider the LS3 at some point, I don't think I'll have it done by this particular installer. I have no doubts that his work is quite good, but it's not good enough to justify that much more than Motech. As far as the new Gen V V-8s, Motech doesn't support them yet.

I will say Gary is quite friendly and he seems legitimately concerned about getting the tune straight. I'm looking forward to the new tune, especially after reading the recent post about the improvements to the Magnuson tune. It sounds like they're getting it figured out. Hopefully Sprintex won't be too far behind. And if Diablosport could crack the transmission...
