Now with speed density, there is absolutely no need for a 3" charge pipe and the better tuning option would be one that is MAF based for light and partial throttle conditions and switches to speed density when you put your foot down.

Hmmm. Debating putting off my install more for this now
@jamesm will this make ur life easier when tuning is the real question?

the newer fa20club kits comes with a revised MAF tube that doesn't have the issues the older ones had. i've tuned both, and i can say the improvement is massive. if you bought your kit recently, chances are you have the new one. it's quite easy to tell, if you send me a pic i can let you know for sure which one you have.

Take some pics

that's a completely different design than any of the three revisions i've seen. the first one had the MAF all crooked and in the bend, it was horrible. then the second (which a lot of people have, revision was made early on) has the maf placed further back towards the throttle body in the same are. it's perfectly fine, better than most actually but there was still room for improvement. the third revision my friend just got in the mail a couple days ago has the maf flange between the bend and the blow-off valve. i've never seen one like the images ecko posted. did that come from fa20club?

Yes, it's a design I helped Toni with.

The reason I came up with this as opposed to the MAF flange between the bend and blow-off valve was due to Full Blown. Their initial setup with the MAF placed between a bend and blow-off valve caused instability with the MAF and the BOV would open, sometimes, at idle. Some guys had to run stiffer springs due to this.

The guys I use for tuning saw the two 45 degree angles with the MAF between them as a problem. This was proven when my fuel trims with the cruise control set would greatly fluctuate. It took a lot of logging and tweaks to get it resolved. On the dyno WOT pulls would read different g/s due to air that would move around the MAF as opposed to through. This was a problem that presented itself even more during cruising as the air could hit a bend and find its way around the MAF instead of thru it.

Ditching the 3" diameter in favor of 2.75" and going with a single 90 creates a smoother flow. Furthermore, the intercooler plumbing tapers down to 2.75" anyway so sticking with 2.75" all the way through made sense.

Interesting... Mine is real close to the throttle body but after a slight bend.

^ that's the same as I have. Not the greatest by any stretch of the imagination.

No 2 fa20 kits are created equal

i've tuned many FA20Club kits with this MAF tube design, this is the second version. it works perfectly fine, in fact my base map is usually within 3-5% just flashing it on using this tube. the new ones are better, but this one if perfectly serviceable. takes a little more effort to get dialed in if you don't already have a good base map, but it can be done (and once it's done, they're fairly repeatable from kit to kit).

Lucky me... Hopefully Bill can tune with this thing. Its starting to feel like "The Money Pit".

It's ok. It's not that it won't work or can't work, it just takes time to get dialed in. A lot of time, probably more than a single dyno session can do. Make sure you have a cable and dongle so you can log and have periodic updates performed until it's fully dialed in. That's the best way that I found that worked.
