is anyone running an aboco mas air meter? if so, how much of a difference does it make, or what other mass air's are good?

Im currently running an Abaco 97mm bell mouth meter! no complaints here. About 2 years ago i was running a C&L meter calibrated for 42s. I had my car tuned at Anderson Ford, and they basically said we cant get a good tune with that meter, its junk. Back then they had a PMAS velocity that they sold me, a 95mm, and I gotta tell you, they installed it and with no tune yet, it ran like a new car! I was very impressed with the PMAS and how it responded. Another year went by and i upgraded fuel injectors and pumps blah blah blah, and I called Anderson to get another PMAS meter, one calibrated for my new injectors and they said they no longer offered PMAS meters, no idea why. Since Anderson is my tuner i opted for there Abaco DBX meter, its very expensive but its also very nice because you'll never have to upgrade meters ever again! Comes with a cd software with very good instructions to! So you can calibrate it yourself if you ever change injectors!
im a firm believer in you get what you pay for. dont mind paying a little more for something that will handle the upgrades down the road

I've used my DBX97 with 42lb injectors and now with 60lb injectors. all you've got to do is hook it up to the comp, change the template and load it.
Only issues I've heard of with them is the selector switch; there are 10 positions that you can load and some have had issues when the positions are loaded with diferent parameters and the switch gets set in the middle of two positions. THe meter gets confused on which tune it's suppose to use.

Not sure what your setup is now, but i assume your like me and are addicted to modying your stang, so i highly recommend the Abaco DBX meter!

the abaco meters are adjustable... not to be used as tuners. IMO they work great if you already have a tuning device (or a tuner that wont charge you an arm & a leg for small changes). If you ever need to go bigger with your injectors you'll already have a meter that can adapt. Select your injectors in the DBX software and just enter in the Abaco MAF output as the MAF transfer in the tuning device and tune as normal.
i dont have any mods yet. just a K&N cold air so far. the mass air is going to be next. wondering if i will see any difference in power with just that?
if you are presently running the stock maf meter now then you should see a gain with the swap to the abaco.

Agree with this. Not saying there is anything wrong with the Abaco meter and if I had a PMS or something maybe it would be an option but been there and done that before.
With a close to stock car if you do gain much it will be due to the leaner A/F ratio. Thats where most of the gain the C&L/Pro M/PMAS meters show comes from. Yes it is less of a restriction but since they change what the computer is seeing due to a different transfer function the car runs leaner and picks up power.
I think the reason Anderson likes them is due to the PMS. It's a better option for someone that buys a PMS and only has the basic setup with no interaq software.

the car isn't going to run leaner using an Abaco meter. While in Closed Loop the O2 sensors are going to monitor how rich or lean the mix is and adjust as neccessary to acheive Stoich (14.64 AFR). Adaptive Learning will remember what adjustments were made and use them in the future when those same conditions are met.

I know how closed loop works, and yes if you still have adaptive learning with a stock tune some of it will get applied at WOT. But the way C&L/Pro M/PMAS/etc. make more power is by manipulating the higher end of the MAF transfer function to lean the A/F out at WOT to make more power. Go in EA and compare the curves for a 73mm C&L(19lb), Pro M 75(19lb), and the stock 55mm MAF. The opposite is true with the meters that have a "SC" calibration, they enrich the A/F by manipulating the curve so it is richer. I don't want to get too off topic here but there is alot of this discussion over on eectuning.org . I am pretty sure I have seen your screen name over there, maybe replied on a thread about extracting SCT tune from chip?
The point being that he is not going to gain any magical 20hp from changing his meter on a stock car. The Abaco won't suffer from the issues some other large meters do though when you are using a meter that lacks resolution at low air flow. I am a budget minded person so I would think he could save $$. I'm not knocking the meters.
Adaptive only learns during CL.
Adaptive does not learn during OL.
'some' of what is learned in CL can be applied to OL, but it isn't as much of an influence as some think... A MAF that has been skewed the way 93GT describes can have a profound impact on WOT...

in regards to possibly running lean in Open Loop, I agree 100%
and with that... if you are not going to get a tune then you should definately have a wideband (or have AFR verified) when you start changing fueling at WOT
