Aftermarket EFI systems. Whos running what??? and feedback!
I am building a new motor this winter and getting rid of my Modified 500efi set-up and going with an aftermarket EFI for more power. The motor will be 700-800HP 540 with no blower. What are people running and how easy is tuning? I am looking at a custom Holley set-up with a 2000 cfm throttle body. Thanks, Jeff Wurl

I used the Holley HP system. Software is awesome (I've used others since and Holley is tops) and tuning with self learn was a snap once I figured out how to properly mount the O2 to keep it from shorting out due to water. I detail my build here: http://www.offshoreonly.com/forums/c...r-project.html

we made our own setup...using a 1000cfm throttle body, 96lb injectors, mega squirt ECM, our own program, not a lot of tuning time this year, so about 82 in 253 checkmate 509 w/MS3 procharger..5-6 psi..
