My interest here is achieving the desired amount of enrichment and the cyl/cyl distribution of the system when entering through the throttle body.
2. Port injection, we already have a 60 psi fuel system in the vehicle so adding an injector(s) to supplement the DI system could be a reasonable solution.
3. High Flow HPDI fuel pump. Magnuson has developed a HPDI fuel pump 30% larger than the stock LT1 (15% larger than a LT4) that's going to be available through Lingenfelter. I'm looking at this with the stock LT1 injectors and then with the LT4 injectors to see where we can get with these components.

With you having EGT, and AFR, on each cylinder, I would think the direct port meth would be the option for you. The only problem with that, at least in my mind, would be the failsafes, or lack of, in the tune. Spraying after the MAF limits you from a few options.
I would think doing a combination of, meth, and the HDPI fuel pump would be ideal, no?
