to MAF or not to MAf that is my question
to MAF or not to MAf that is my question 
just finished the final mock up of all the chgarge piping and im down to the last pipe and my knowlede runs out.......do a use a stock MAF???
or do a loose the stock MAf completely and gor with just a 3 bar map sensor set up??
going nuts cause i dont know enough about this what to do??any advice would greatly help need to knolw what i should do before i finish this last pipe!!!
where do i get a 3 bar map an dwireing harness???
I'd recommend a truck/Z06 MAF to keep best driveability if you are going to keep it on the street primarily. Many others will say that gives up some power... but it also retains a margin of safety to help deal with changing weather conditions.

what year truck?
its manily a track ....nice day/night street car....

ok i know you know what your talking about
my set up is...
mtiu iron block built for boost all forged yadda yadda 6.o heads springts retainger yadda yadda custom cam from cam motion
6.0 ss truck manifolds flipped cermanic cfoated extrude honed
turbo centered in front t-76 for now but room to go to 91 thumper.. later one
all cutom mandrel bent stainless tig welded yadda yadda
speed inc race tank bosh single 420 fuel pump speed incd rails z06 intake
12 bolt 373 gears
does that help???
I feel the need to hijack real quick. I've read quite a bit about MAP sensors on here. what is the difference between 2-bar and 3-bar? When is one necessary over the other?

It plugs into the back of the block behind the intake. You have one stock... its jsut a 1 bar set up thought, swap it out for a 2 or 3 bar

it hooks into the back of your manifold where the 1BAR map sensor is located... The way that your computer is designed is if the Maf sensor fails it goes into SD mode which therefore reads off of the Map sensor...
You can get a 3 bar map from a typhoon or syclone... You can get better throttle respnse from a SD tune but if your temps change a lot where you live then I would tune with a maf...

awsome!!!
anyone have apart number and is it a direct plug and go or do you need a harness adapter or something??
yeah temsp change alot
so should i stay with my 99 ls1 maf or get one from a truck..
He's the uber moderator...COUNTRY BOY...you tell em, read those FAQ's dammit!
Hmm I thought 1bar is 15psi as I have 1bar springs in my tial gate in my 97 talon and that is 15psi roughly. So would have thought 2bar would be like 30 and 3 bar 45.
I was thinking speed density no maf in my 99 ta.Might stick with maf in my 97 talon not sure yet there either.I can't see speed density cars running that bad buddy has 93 trans am with paxton blower and its speed density stock setup.It runs fine all the time.

Yeah bar stuff is confusing. psi is simpler. and 1 bar is not exactly 15psi its close though.Thats my minimum boost on my tial gate. Max is supposed to be think around 22 or so then you up the springs to get higher.
In maps sensors, 1 bar gets you 14.7 psi that is atmospheric pressure....that's why a 1 bar map doesn't read boost pressure as that is pressure over atmospheric. So a 2 bar will read 14.7psi of boost and a 3 bar will read 29-30psi, etc. You have to subtract the first 14.7 psi for atmospheric pressure.
Isn't there some kind of sensor to measure air intake temperature, or is that part of the MAF? I'm a little confused why the MAP only setup will get problems when the weather changes. I know changes in air temperature change air density, but I thought the MAP system had that taken care of?!
