Today I tested the difference between SD and MAF mode both in open loop (Dyno inside)

The maf can take a half done ve table and get things close but when you take a dialed in SD tune and then calibrate the maf I feel things will be right then. I am tired of tuning my car 24/7 running in open loop because of temperature changes so I am putting the maf back on just like HumpinSS. ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)

I understand I was speaking of the load dyno because Ive been there and done the 6-8 hour tuning thing, LORD do I remember LOL. LOOPPY LOOP around Waldorf and 210 until i got it right LOL

Did you replace the MAF with any sort of tubing?
I honestly wouldn't expect much of a difference with the same induction setup i.e. different types of control but with the same induction configuration.

hey guys,
why is it then that the boys in Austrailia are having such good results with MAFLESS tunes down there. I mean they all run MAFLESS down there and they've been playing with these engines and computers longer than we have.
On my car I am considering running a 2 bar Map with a Speed Density tune.
The guys down under are not only reporting nice gains but also getting a lot better fuel economy too.
