A while back, I was reading a thread from a tuner about some experimenting he has been doing with maf housing sizes and different Maf's it was verry interesting to say the least.

Well I've been doing some learning, and testing and wierd things happen. Basicy a calibration for a SCTBA2400 in a fatory housing will work well and get you in range for fine tuning, take that same Maf out of the housing and put it in a larger diameter tube and its way out of range and more changes have to be made to the Maf xfer to get it back where you need it.

Take that same calibration for the SCTBA2400 in the larger tube, and put a 2600 in a stock housing in its place and that same calibration seem's to get you in range for the SCTBA2600.

A larger tube seem's to extend the range of a maf, but at the same time will be in the lower load table's and lean out the tune due to less counts?

I guess I'm kinda confused. I can get any of them right in the tune, thats not the issue i can put the a/f wherever I want it and ramp it however I want without raping fuel tables into submission which is nonsense.

I just want to understand this more, there's gotta be positive's and negetives to both ways, if not basicly what I'm saying is I could use a SCTBA2400 or even a Ford 90mm maf, put it in a big azz tube and run as much HP or CFM as I want without pegging it out. and totally eleminate the need for those rediculiously large maf's like the SCTBA3000 that get all funky on driveability and low end resolution.

Maybe my logic is wrong? I could be wrong, and some of you in the know, feel free to rip me apart, I just want to understand this better.
