speed density vs mass air bought a LT1 without wiring harness and computer or MAF. rebuilding the engine for about 400 hp and am wondering if i can choose to go speed density or MAF depending on how the computer is tuned?? which system would be better??

ive heard of people going with SD tunes and running very strong. I was thinking the same thing earlier today but dont know much about it. hopefully somebody else will chime in with experience.

I wish I could find it but I had a diagram of the was speed density calculates air flow VS MAF, MAF was a 2-3 step process as speed density was like 15+. MAF is more simple.

But is simple always better? Simple leaves room for error. Complex can cover more areas. ECM's are able to crunch numbers fast enough where 3 of 15 doesn't really matter.

SD is harder to tune..but can help depending upon the intake setup. if you flow so much the maf is a bottleneck, then you should go SD. otherwise, maf will make it run better part throttle most of the time
