I deleted your post Paul because it was a reply to a post I deleted for being shop bashing. Thus it was out of context once the post it was in reply to was removed. Any further questions, and just any questions on moderation in general, PLEASE PM ME.

Thanks

Actually, it was vendor bashing (though doubtfully a vendor on here). But it most certainly wasn't without warrant. It was more of a warning.

Anyways, back to the topic. All intakes would benefit from tuning, but not all require it. The list that was taken from Unabomber's Manifesto in the second post needs to be revised as
2 of the listed ones do require adjustments and other intakes that don't are not included due to lack of updating on Unabomber's part.

I have a sub question for this; When you get tuned for an intake (or just in general), does it still go full lean when you get off the throttle and let the engine slow you down? Prior to intake it was reading 25's on the Cobb AP (which reads off the O2 sensor after the cat and is inaccurate, I know), but seems like any time idle or cruizing it's perfect. I now have an AEM wideband and it only reads up to 18 for some reason so it goes full lean in the same scenario but I can't tell how much... Is that normal or should a pro tune fix it a bit? I will have to wait for the tune another week I think

The real question is.... why do you need an intake in the first place?

^^90% of the intakes out there do produce power.

I went with aem for my 09 wrx due to the fact aem seemed to nail it with matching stock set up and after 30kms no problems at all. Now I have a cobb stage 2 set up and had to remove cai for safety. I ran the car for a week with stage 2 and cai with no problems, smooth and pulled hard and after going to stock intake it seems to lack something.....oh and afr readings if I remember where pretty much the same. Anyone else try this intake out?

Do you have a wideband? If not, any AFR readings you're looking at are inaccurate. The AFR gauge on the AP is useless.

I could finally get a tactrix cable and do a couple pulls with the perrin cai on and then swap the stock back in...I have an innovate wideband so it would be accurate. That all hinges on me buying a tactrix.

Oh and to Smokin' Joe's post in March, yes the car still goes full lean when you're off the gas. It goes back to stoich when you get at or below 1700 rpm's so under that point it will try to hold 14.7:1.

like wetdream was saying yes it goes full lean. i have an innovative wideband and it goes to 21.9. when you lift off the trottle the ECU shuts down the fuel injectors while still in gear. if you coast you'll be at idle (14.7ish)

It's fun to see my egt gauge drop below 400 (bottom of the gauge) when I'm coasting down some of canyons out here. Direct result of zero fuel going into the cylinders.

I have an 09 WRX with an AEM UEGO, Tactrix 2.0, and a K&N Tyhpoon.

You will find that your AFR's are probably correct but your timing will be all over the place on the stock tune. The car will pull timing and you will probably have alot of KCA variances. I also noticed minor amounts of FLKC (around -1.0) at certain RPMs. I got a tune and it cleared all the FLKC up and KCA is very stable now.

These cars run about 14.5:1 up to 4000RPM then transition to 11.4:1 after it goes OL around 4500RPM. That is LEAN for WOT underboost. That is the way they were tuned from the factory. That's why the power band is so bumpy. A tune will make it smooth!

Bottom line I don't think you get much out of the intake without a tune, except the cool sound of course!
