However...GM engineers (being an OEM) have a helluva time developing a tune that will allow this parts kit to pass emissions. My guess is the story hasn't changed for the LT1 "hot cam" idea...So, it sounds like they backed off, and just put it upfront that you'll need to get your own recalibration.
And of course, once you do that.....the powertrain warranty pretty much goes out the window.
I don't think they're trying to screw anybody. I've spoken with these guys on multiple occasions and they'd love nothing more than to offer a warrantable calibration straight from Chevy Performance Parts.

Do you have any sources that could enlighten the community what more is needed with this package in order to complete a install on a "off road use only" LT1
Would be nice if they posted the instructions with the equipment online so we can read through them and see what else may be required.
