Not to add any fuel to a potential firestorm here, but you really do not comprehend the entire picture of this situation.
First, the few vendors and small businesses that do turbo Buick work make a very small profit, if any, for their work and products. Add in the crap we have to endure from un-informed members over stupid comments and abuse we take from them makes one wonder if we should even try to help?
Bad enough some "enterprising" people take our intellectual property and build knock-offs in China, now you are offended that someone will not make public tech info that cost them many hours and $$$$ to develop and refine?
Yes, there is some engine tech info about how to build an engine, but you do not see engine builders posting details of a complete engine build.
First, if I post something relevant about an engine build, some "backyard" expert that built their own engine will dispute that because he did it different, and it is still running.
I know engine builders like DLS, TA Perf, Ken D. and others like myself, will not give out, or publish, tech details unless you buy the engine from them.
The tranny builders have a right to protect their property as do others.
Bottom line is, you should be grateful someone has done this development and testing to make a product do MUCH more than was ever intended, and it is available to you - just pay for it.
