Could someone explain it.
Also what sensors do you keep and which ones to get rid of.
I know the MAF goes, what about the o2's, knock sensors, MAP, IAT, ect.
Thanks

Normally everything stays in a SD tune unless you are running a Open loop SD tune then your o2's go also. SD tunes are usually used in FI builds and stroker high HP application.

There is a ton of threads as to what is better etc in this section and online if you want to read in detail.

Thanks Bill
I want be running a MAF with this Super Victor and 4150 TB. Race only car.
I've read alot on the SD tunes, but still confused alittle. Most people are worried about idle and street driveability with SD tunes, that I've read. I don't care about driveability.
This car will stay between 5000 to 7000 rpms most of it's time.

If done properly, you shouldn't be able to tell the difference between MAF and SD. I've tuned several carb style throttle body cars. They run real well for as radical as they are.

A good SD tune does not lack idle smoothness and street driveability whatsoever over a MAF tune.

Great information in this thread that crystalizes why the hybrid tuning system is currently best for my street car application.
