Do most see gains with 85MM MAF? Do most people see any gains when they add an 85MM MAF AFTER they let the car relearn and acclimate to the new settings? Thanksl
Re: Do most see gains with 85MM MAF? I have a SLP 85mm, don't notice any extra power when I swap them at the track-not even a .5mph.
The increase {if there is one} might be too small to notice if you don't run them back to back in the same conditions. BTW, I'm pretty much stock-you might see some better gains. For me it was a waste of 135 bucks over my home ported stocker.

Re: Do most see gains with 85MM MAF? I have one and noticed a good sotp at first but since I dynoed running very rich I put the stock meter back on. The car feels weaker up high but stronger down low. I'm gonna stick with the stock one for a few hundred miles and see it my mpg changes or not. If I were to do it over again I would have got a Pace performance mas. I'm always find pieces of leaves on the inside of my lid so I'm not gonna run one without a screen.
Re: Do most see gains with 85MM MAF? From what I see, there's no consistent pattern.
It has potential to improve airflow, but if it
wasn't the big limiter to start, it won't be the
biggest improver. I think the people who get big
gains, get them from messing the WOT mixture
around (a true-calibrated aftermarket MAF should
be identical to the stocker in terms of signal /
airflow, many seem to be not). Nowadays there are
other ways to modify mixture than just hanging on
a different MAF sensor and hoping lean is better.
Plenty of people who go fast say the stock unit
is perfectly fine (if you're not forced induction
or sub-11 sec then this almost certainly applies).
But that never stopped me from shopping, and you
might not be able to rest until you bolt on every
bolt-on either. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

With a big cube motor, go ahead and splurge. Be prepared to slightly tweak your tuning.

Re: Do most see gains with 85MM MAF? I just installed the TR224 @ 112 cam with SLP long tubes, high flow cats and Loudmouth (this resonator will be replaced, I can't stand the rasp)
anyway.... My question is, besides a Lid, I still have the stock TB and MAF but I picked up an 85MM MAF when I got the headers. Should I run the 85MM or will this give me a lean condition?
I also have NOS, but have not run it yet on this set-up. The car was just started with this combo this week by the way.
Thanks

Re: Do most see gains with 85MM MAF? Vin: The SLP unit is calibrated so it SHOULDNT be to far off from your stock unit. Granted its gonna need some tweaking. My LTRIMS with the stick were -6 to 0 and with the SLP they jumped to 0 to +5
I did the ported TB and SLP 85mm and picked up 3mph at the track, but I also went from nittos to et streets at that same time. So my guess would be I maybe saw 5hp from it and maybe 10 from ported TB. The more mods the more the 85mm would help. if you are stock, its not really gonna giva ya 3-5hp if that <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
