MAF or no MAF?
MAF or no MAF? Ok I've been looking at some of the build pictures and I don't see the MAF on a lot of the builds. Does this mean that there is a way to run these engines without one or are people hiding them?
I am running a turbo on mine and may consider going SD later on after I get better with tuning. I'm about to plumb my intercooler so I wanted know if the MAF is required?

I am not running a Maf sensor on my setup. I purchased a after market tuner (EFILive) to disable a few other Items I.E anti theft, emissions, etc. At the same time I did a Cam swap so tuning was required. I found it was easier for me with the rougher cam to go a straight sd tune and upgrade to a custom operating system as I had a little bit of trouble tuning the maf sensor to behave at low rpms. After a few ve logging sessions the ve tables were really dialed in well and I have been really pleased with the drivability and results. Just my 2 cents though, to each his own.

I'm not to saavy on tuning the maf w/turbos. There is a drawback with a set pcm air acceleration limit . The best bet would be to bounce it off some of the turbo guys here and see what they are running or recommend. See this thread https://ls1tech.com/forums/forced-in...-air-flow.html . In my case I wired the engine up in the car as it was from the factory w/maf and stock cam with minimal tune mods-just enough to run it no driving yet and see what PO codes I received and after I knew there were no gremlins w/ the install I started modifying and switched to sd. As it is always nice to rule out the human error before you throw in more variables. Best of luck.
