for my 408 custom cam, L92, L76 intake, 90mm tb, `1 7/8 header, svo 42 injector setup what would be best to use the Maf or go SD

see with a 90mm tb the inlet for air needs to be 4" and my K&N FIPK isnt that large and neither is the MAF should i eliminate the MAF and tune for SD for this new setup

 

SD for sure, I just got through tuning the Wood Hauler's 408 for SD and it makes a difference. Idle tuning was a little tougher but tuning the VE isn't bad at all and drivability is still great. When we do his Victor and 4bbl and possibly a new cam/heads setup, I will use EFILive COS3.

 

On a 346 we actually found that the stock 75mm MAF was a restriction. Not the fact it was in SD, but the fact it was a smaller opening then the intake/TB. We changed the MAF to a 100mm MAF/4" tube and the car picked up 16hp. This isn't common but it does show that on some setups it can be a restriction.

 

yea that is what i was thinking, figure if i go SD then i can make a 4" inlet and that will allow my motor to Inhale very well and with 1 7/8 headers and dual 3" i should be able to exhale just as well

im hoping for mid 500s to the wheels NA with new setup

 

go speed density, is much easier to tune a cammed motor..

 

did you remove your maf? if so did you relocated the IAC or etc

 

on your IAC use a pair of needle nose pliers and pull on the two ends of the IAC that the connection plugs into and it will come out..for the longest time i left it all disconnected and never effected anything, for the a/f vs inlet air temp cant remember what exsactly its called but i had it all set to 0 anyways..never effected a/f, spark or anything with it plugged in or not..

 

sorry yes i removed my maf sensor, and now i do have it hooked up buts its just settin underneath my air filter

 

what steps did you follow? the ones in the help or ones off line?

 

you got hp or efi live? i got efi live at work..i went with through all the steps in efi lives tutorial..i went with an efi live custom os also..
