Reply With QuoteFor me it was worthwhile, and the changes still seem to be in place. I don't know if it would apply to everyone but it worked a bit for me...until I get my S-AFC.
For those that did the MAS screw mod about 2 weeks ago... How has it turned out? Did you notice any real changes (better or worse)? Is this something to pursue (if you have a CAI and exhaust set up)? What do you think?
Thanks for the responses in advance!

I'm still happy with it. The low end power is still there. My gas mileage is still at 24mpg, slightly better than my last tank. I'm actually thinking of backing it out another couple turns.

Thanks for the feedback! ... this mod is definitely something to consider when (if) I ever get a CAI and muffler!
I did mine like a while ago, and have had no problems with it.. i would suggest watch out on how far u back the screw out because u will run really lean and ur idle will get all wacky on u..

Hmmmm I am lost.....Could you guys fill me in..?? I figured this mod had something to do with running rich/lean but where is the screw???? Does it really make for a better performance??

Do a search on MAS screw NRG. There are photos and performance results there. I think it makes a difference on my car.Originally Posted by NRG

i did this some time ago cause my car was running super rich due to my DP. i guess i saw some difference. Just beware, make sure you carefully document how far you backed it out cause if you wanna get a afc or afr you have to readjust before you hook those up.
I am doing mine today......But I just thought of something......The rubberish seal on the screw must be there for a reason. If we rub that off, maybe some air will be leaked??
Another thing is do you guys have the screw flushed or 2 thread more than flush?

it is just a silicone cover to prevent YOU from tampering with it. just cut it out, and if you are paranoid about that then just take some silicone sealant from home depot or something and fill it up after you make your adjustment.
FYI, for that to leak your intake would have to be under pressure like if you were boosted, like i will be next week......wwwwwwwwwwooooooo
I flushed mine and drove around for awhile and I didn't notice any difference.........

did you reset your ecu....anytime you make an adjustment like that you should reset your ecu
everyone else agree?
I didn't reset mine. Just backed the screw out to one turn past flush and drove.

I didn't reset mine...actually I never reset mine after mods...

Alright this mod make any difference in the leaness or richness of you're car. The reason i know this is b/c my brother in law just got a couple tachs put in and one of them happened to be an Air/Fuel Gauge. He was running a little rich when he came home and I was truning the screw all sorts of ways and it didn't really make any difference in his rich or leaness. But I do believe it helps with you throttle response b/c he mentioned to me that his car feels like the response is a little better.
Not necessarily true. The A/F meter measures in the closed loop operation. That only happens when your at WOT. when you're not at WOT, the meter is not accurate because it can't keep up with the number of measurements per second that are taking place. If you had hooked an AFC and changed the screw you would have seen the difference it makes.

Update: My MAF screw is out about two turns past flush. First tank of gas 24MPG. Latest tank of gas 22MPG. Not a major change, but something to keep an eye on. I'm also due for an oil change in about 500 miles, so that may be a factor. Just providing info.

I gained 2 mpg after the synthetic oil change

So Fishboy AFC's measure the air fuel ratio more accurately? Or is that when the car idel's and you aren't at wide open throttle that's where the AFC helps compared to the Gauge Meter.
Yes, of course they do. That's one of the reasons they cost $300 as opposed to $35. An air fuel meter will be accurate enough at WOT unless you have a bunch of mods like headers, boost, etc. Then you need an AFC to adjust and tune all that. The AF gauge just looks at it, can't do anything to adjust it.
