I have the Accel TPI kit installed on my '69. It's really slick compared to a stock TPI setup. With their software you can adjust your timing curves, fuel curves, warm up enrichment, air temp adjustment, cold start mixture. You can choose open or closed loop. Right now I'm running closed loop until about 70% throttle, then it switches to open loop and really pushes me back into the seat. You can save/load different settings from a laptop whereever you like -no opening the hood. I would definantly prefer a TPI setup over a carb. I could never rebuild a carb but testing sensors and such is easy. Beware though, an aftermarket EFI setup can get pretty expensive.
