Post # 20 has a Microsoft Excel .xls file if you have Excel. I've also re-attached the file from Post #20, see below. I just tried using the attached .xls, seems to be working for me.

Please update me with your progress.

Using this spreadsheet, running 100% duty cycle on my injectors indicates a supported horsepower of 306. I feel I have been wronged. I purchased a rebuilt TBI unit from SPR performance, specs below:

46mm TBI Kit
New TPS, New IAC, TPS adapter, 65lb flow-matched injectors, 18psi spring, thinned shaft, bushed shaft, 1/4" pod spacer, shaved air horns, adj reg cover, custom cut 46mm base gasket

I specified I was using a kit from Summit Racing (SME-K-355-400), link to cam specifics here. I'm considering selling all the GM TBI parts and going for an MPFI self learning kit from Fast.
