Hey guys. Its been awhile! My car is finally at a shop, second street speed in perkasie (www.secondstreetspeed.com) to get dyno tuned! He ran into a problem tho in which my maf is getting pegged at 4k rpm's and that its not working very well. He was saying something about it should be around .8 volts or somethign at idle and it was really at 1.5 or something. I dont remember exactly.. Anyway, What maf would you guys suggest? I was looking at the 80mm Pro-M's but they have a filter right attached to them, and I have my air temp sensor BEFORE my maf so that wont work right. I need somethign that I can attach a hose to on each end. I saw the 75mm bullet maf's but some have said that they arent as good as the regular ones. Does anyone here run a 75mm pro-m and can give me some feed back? Thanks again!
 
You have gotten correct info about the bullet maf.

Some, but not all, have had issues with that meter.

The electronics on the 77/80 meters are more accurate.

Went through all that with ProM's tech guy before I got mine.

As for the act, you just need it placed somewhere in the pipe between the maf and throttle body.

I missed the blower part of your combo :bang:

With all that stuff between the tb and filter ..................

If you go with a ProM meter, you wanna look for the shorty version to conserve space.

Some tuners like to have the act after the blower so they have the ability to fine tune the higher blower output temps in the pcm tables.
