Decided I like the added bonuses of a MAF car over SD because it makes adjustments based off the meter no matter what altitude the car is at etc....But after 500rwhp they tend to go mad, with the BOV and boost etc....so I went with a slightly expensive custom MAF. Wondering if anyone else has had any experience with this and how it turned out. I have heard of people tuning cars to 1000rwhp + daily drivers on MAF and figured why not. I think it will be impressive and provide me with a consistent performance.

What MAF is it? and how is it "dual curve?

The whole "they go bad after 500 hp" is a myth.

The problem with the gen III is that the MAF pcm limit is 67.7lb/min of air. Regardless of what MAF you use you will max that out and have to scale the tune.

Abaco?

If it's an Abaco I'm all set. Bitch to tune in.

Alot of cars we switch to a LS3 MAF and use a bigger pipe to cut flow down across the maf.

how exactly is that cutting flow down to the MAF?

Abaco Maf looks nice

Its a Pro-M. Meter. It should allow the car to run a consistent A/F depsite weather conditions etc. Apparently its what people are using to tune cars with FI. So far it and the Abaco seem like the best choices. There are some other Pro-M models that really arent that great, but this is supposedly the good one rated up to 800hp. It sure costs enough.

^^^ Yup, Mine, stock maf less screen, 722 RWHP on 14lbs...

When you say 'its what people are using to tune cars with FI', are you referring to GM vehicles, and if so, who are 'people'?

No offense, but I dont think I have ever seen a build here that used a Pro-M. I use them on Fords all the time, but never on a GM. FWIW, the stock GM MAFs are kick *** pieces for the most part, and tend to be more consistent than most of the aftermarket stuff you'll find out there.

There are alot of tuning myths out there on forums lol.

Amen!

And, I have never seen an aftermarket MAF that wasn't crap.

Like said before you can use a LS3, LS7, LS9 MAF sensor (card style and use a larger inlet 4(inch) this will lower the Frequency and to get around the 512g/sec/67.7lb/min limit you can scale the tune by a percent.

Or go SD, thats what I did and i'm very happy with it.

yeah the "people" are mustang owners. and hey, if it doesnt work, i have the oppurtunity to get my money back and go with one that will. i am for using something in my build that noone else has used. i dont mind being a test pilot at all. If it doesnt work I will try the abaco. i read about it. both seem to be good pieces. I will be real strict about it too.

we pegged that mass air from Pro-m out in about id say....half a pull. haha. went with a 3 bar map.

Mike@Diablosport

At what power level. Engine combo? What pcm are you using?

i pegged right at 599rwhp today and the head lifted. we had 22 degrees of timing which needs to be lowered even with the meth. we were in the process of tuning and splash. this is, or was a stock bottom end with d1sc. its all in the sig. and the wrist.

Mike@Diablosport

Damn son. Thats nutty, we made 615 rwhp on a P1 at 7 psi on a stock 346 LS6 at 12 degrees/pump gas. FWIW, that was on a stock 85mm GM MAF. Car drove perfect.

Yup, Because that was a good safe tune, to the OP of course now you know, 22* of timing was way too much even with meth, On a stock bottom end, I probably would of stayed at 16* or so...Also keeping your A/F safe too..
