I'm old enough to know my way around a Holley carburetor but didn't like the constant fiddling so I was an early adopter of the FiTech TBI. I went through 3 TBI units and 2 wiring harnesses under warranty before I sold it to a forum member for $100. FiTech is still in business so I would have to assume improvements have been made. I currently run the Pro-Flo 4 that was flawless for two years until it wasn't. This summer the Edelbrock return rail mounted fuel pressure regulator failed and a direct replacement being backordered indefinitely I had to convert over to a external firewall mounted unit. In that process I must have moved the PF4 distributor extension harness connector onto the top of the fuel pressure sender unit. The end result was me bringing the trailer to the car after it stopped running at 2 autocross events. The car ran perfect until it got heat build up and then wouldn't run until it had cooled for hours. After a lot of cursing and hair pulling moving the distributor extension harness connector an inch off of the top of the fuel pressure sending unit made the car 100% awesome again! Multi port fuel injection is the best thing on earth when it works, and a head scratcher hair puller when it doesn't. Given the G forces of autocross I'm going continue on with multi port EFI for now.

I originally purchased my Holley 650 double pumper about 15 years ago when the price difference from EFI and carb was greater. That being said the carb has been pretty flawless save from one vapor lock event in 15 years. I thought about “upgrading” to efi but I had read enough stories about people having a bad ecu and replacements being back ordered that I decided to keep what I have but improve it. So I’ve installed an AFR gauge to help with tuning and I bought a bypass regulator etc to make a return fuel system to help ease my mind of vapor lock on those 90+ degree days.

For me it was a decision based on what I can troubleshoot and repair on the side of the road along with not wanting to lose the nostalgia of having to deal with a carbs personality. The day my 10 year old was helping me tune the carb this past summer I knew I had made the right choice. He’ll be one of a few his generation who have even touched one probably!

I'm all in on Multi port EFI but think those not pulling G's could do well with a carb and a return style fuel system in eliminating the vapor lock that happens with ethanol blended "street" gas. I'm a big fan of in tank fuel pumps as well. I wish I had done a little more tinkering with an old 650 DP I had from back in the day before I sold it to a forum member just to see what was possible.

EFI when it works is awesome though!

I chose, and will continue to choose, a carburetor. I own a vintage Mustang to drive a vintage Mustang, not a late model Mustang.

A brief observation..... I'd like to see ANY of today's comparable vehicles with a 3.00:1 final drive ratio in top gear, manage to get the same fuel mileage on a trip that I do with my Mustang. If I limit myself to 70 mph and tread lightly on the skinny pedal I can squeak 20 mpg on the highway.

My 2021 F150 with a 5.0 with both direct and multiport fuel injection will squeak out 24 mpg in similar situations.🤷‍♂️
