Finally made it through the thread.
Looks like the goals of the project were met with great success.
I know you said you are pleased with the performance with stock fueling (excepting a desire for earlier onset IIRC) have you considered a charge cooler?
I ask because unless you luck out with getting the performance via a timing adjustment it will likely require more fuel to bring the turbo on earlier, which will likely elevate the EGT.
The other options being a tighter A/R on the turbine housing, or something whacky I've read on the internet.
I hear and read stories of people using the smog pump off a gasser, and plumbing it into the exhaust manifold before the turbo. Some people claim the extra gas, working gas, in the form of air, helps the turbo come online.
I've heard the same thing about water injection though, but I'm not sure how you would rig that up without having to flip a switch everytime (maybe a microswitch on the accelerator like the Nitrous guys use
).
I don't know if any of that helps, I hope it does, and I wish you continued success with the project.
