I love my TWM/Borla 8 stack with Big Stuff 3. Not a lot of talk about the BS3 system but it was the system my installer was familiar with so that's what I ended up with. As I hear, the BS3 is popular with the racing crowd. I think having somebody to turn to locally with experience in tuning with the system you have installed is a big plus. For me the initial learning curve was somewhat steep as I had no prior experience with EFI.
After a couple dyno tuning sessions and playing with the fuel and timing tables the system is running very well. Starts right up every time and idles smoothly.
Has a solid flat tappet cam that the cam mfg. says with a carb would "shake the fenders off the car", but with the 8 stack individual runner EFI system idles with very little lope and is very easy to drive on the street.
This way to go is not cheap but has it's advantages over other systems. Just my .02.
