For a single turbo SBC application in the 550hp vicinity, is a MAF based EFI system better to use than a speed density based EFI ?
I expect to run boost in the 7 to 12 psi range.
Once I finish this build, I don't mind spending $500 on a professional tuner to dial everything in for me.
What I don't want is endless amounts of tuning and tinkering, or a system that a professional tuner can't get to work well because it doesn't work well under boost.
If I ever change this build, which I doubt, it will be a one-time change to a dual turbo setup with better flowing aluminum heads, years down the road. In which case, whatever EFI system I get now, will need a major upgrade or replacement anyway.
From what I've read so far, MAF is more self-tuning and adaptable to different driving conditions, but speed density seems more popular with the hard core speed junkies.
The Mass-Flo, Holley Commander 950, and Accel DFI systems have my interest peaked. I'm intrigued by the mass-flo system claims to be self-tuning, but in a boosted application I'm not so sure it can deliver. FAST and BigStuff 3 look great, but above my budget of 3K for a fuel and spark system.

Any of the aftermarket systems that are 'boost friendly' will be fine. The OEM stuff works but requires more tinkering, but is nearly free. Originally Posted by turbo67camaro
