Hey guys, i was looking at maybe a little upgrade with my mass air flow sensor. I'm about to finally put my aluminum intake elbow on and figured a little extra air flow would help too. My question is are aftermarket MAF that claim 10-15 whp, such as http://store.summitracing.com/partde...5&autoview=sku, worth the money? Do they actually work? Is there anything i can do to the stock maf to help it flow a little better?

Thanks
Chris

 

not worth it. your stock maf is not a restriction and the only thing you will gain is difficulty in tuning. for $300 you could pick up a used nitrous kit and get some real gains (or even a cam/roller rockers/tune)

 

Agreed - all I've ever heard is that it's a huge mistake to replace the MAF because it causes more issues than any performance gain.

 

also, save the headache and leave the stock one STOCK! dont take out the screen; it's there for a reason

 

Yup. Mess with your MAF and your fuel trims will show it.

 

I have a perfect used one for sale, for half that price if you want to try it.

 

As far as the Granatelli MAF sensor, it MAY produce a HP gain. It does that by intentionally miscalibrating (lowering) the high end flow numbers, to help lean out the overly rich stock WOT (PE mode) target A/F ratio. Its sort of hit or miss, at best.

You can get a guaranteed 10+HP gain by doing the same thing with a PCM tune - lean out the PE mode target A/F ratio - for about 1/2 the cost of the Granatelli.

Please do not offer "parts for sale" in the tech forums. Send a PM or e-mail.

 

good to know. i was really just wondering.
