Big Stuff 3 vs Holley EFI for LS engines

Jason Shepard · 09-28-2021, 08:32 PM

Im currently running Big Stuff, thinking of switching. Should I switch? Or would I be better to spend my money elsewhere? Any advice would be appreciated!

Reach out to Robin Lawrence on this forum.
He is the Holley EFI Rep and an expert on the system.

Robin is great to work with. Very helpful. I've never had a chance to play with a Big Stuff system but I've had a Holley on a couple different cars now. I'm by no means an expert but the software is very user friendly and easy to navigate. It will be going on our super stock car once we get our new combination together as well. Their actual tech support isn't the greatest at times. But having a guy like Robin or Jeff Niceswanger who are both very helpful along with a online forum that has many really sharp guys with tons of experience make it worth while in my opinion.

Holley was better on our LS1 and our COPO across the board et mph and horsepower. Holley was the best for us and Robin always is good to work with when we need help from start to finish of our projects. The holley system is compatible with race pack also !

How much faster?...I would think either one would be infinitely adjustable. In my mind the guy with the laptop would be the most important part of the equation. I have BS3 Jeff Taylor did the program at his shop. I had to have the idle to 2500 RPM fuel curve cleaned up a little. But if the Holley is indeed faster,I may have to consider it

Of all the systems I have worked with, the Holley is by far the easiest. It has a crazy amount of capability.

I can't tell you if one is faster or not because we made the switch from BS3 to Holley at the same time that we went from an automatic to a 4-speed - but I can tell you that the Holley system is WAY easier and more useful in terms of what you can do with it. Their user interface is superior to the Big Stuff 3 program, in my opinion.

Hot topic this weekend! If you are not running closed-loop this is a no-brainer. If you are, how much is it correcting?
