go maf-less?? Would there be any benefit to running without a MAF sensor? Can it be tuned out? Just curious.

Yep. All the rage down here.....apparently good for another 20rwhp....and it seems that all the mafless cars go faster with better mph than the maffed cars.....not that I would know.....I'm probably the last person in Australia still with a maf!!

so um do you guys with speed density know something I don't i don't know if this is comparing apples to oranges but on 87 and 88 stangs they have speed density and with mods done to the car it runs like **** so everyone has to convert to mass air how do you guys do it on the ls1s just curious maybe i can 1 up somebody by keeping speed dens
Ford speed density computers vs GM speed desnity settings on the computers are night and day different of how they work.
For a SD mustang, adding a MAF is the first thing to do, and is HIGHLY reccomended. For the GM, it is a tossup, with good results both ways.

What HPT does is runs a better resoultion in 1,2 and 3 bar setups. Deleting the maf isnt just the push of a button either. You have to set the mil to report 1. This will tell the pcm to revert to the main VE table. Then you start building your table from there. I am building a 2 bar setup. Still a rookie at it but I dont post much about tuning. But thats the general idea.

The way I see it is : MAF removed, car response goes up and its up to you to dial in the VE and get everything to where the idle and part throttle is 14.63AFR and WOT is what you want. Along with everything else the way you want.
With the MAF: the car response is a *almost unnoticeable slower response and with the MAF in it is measuring the air flow and determining how the engine should run with how the throttle is being pushed and other tests/inputs
I personally know Nick williams and he is running the MAF (recalibrated) and as inspections I have put mine back in, and WS6FirebirdTA00 and me are going to dial it in(recalibrate it) this coming week.
Just to let you know, my best dyno was with it, as my VE dial in was a little off on my first go. BUT I had only lost 5HP and 9TQ with the MAF gone...which was probably due to my bad AFR across the board
