[Not a bronco]

I use fitech fuel injection on my 72 blazer and it works pretty good but there are a few little bugs that are difficult to get rid of if you don't know what you're doing.. (like me) I've had the go EFI 400 hp with fuel command center for nearly 6 months and I still have a little bit of hesitation (but I'm figuring it out) when giving it gas while coasting, and the fuel pump was overheating but I solved that problem by removing the float and running a fuel return back to my tank. But it performs a lot better on cornering offroading and drivability overall. But their customer service is pretty much garbage everything I learn about the unit is from a group of very smart owners on Facebook who try really hard to help.

Have you looked at holly sniper EFI? That something I wish I would've waited a bit longer for, but I don't regret buying the fitech it's just a little fickle at times
If you have any other questions I can try to answer them
