I'm guessing that If the engine doesn't run well anymore or my gas mileage dramatically drops...I can tell the ecu didn't reset....???
Just remember to let the car idle for 5-10 minutes before you drive it. Regarding Gas mileage....most likely your first two tanks are gonna be significantly lower...I say that because when you hear how aggressive the new intake is, you're gonna jamming the gas all the time, and winding it up. I typically averaged about 23-24 or so in town, prior to the intake. MY first two tanks after wards were 20.x But that's because I was shifting at 4-5000 rpm's, not 2800. Once I got over the noise/aggressiveness, the gas mileage went back up to 23 ish.

wooopieee!
It worked like a charm...it's been running great! I was a little sceptic at first. Now, if there would be a diagram for the tc, I'm sure that would help out future installers alot. THANKS FOR THE HELP EVERYONE!
I have a tC and I did this twice. I looked at the back of the fuse box for the efi fuse. There are only two 20 fuses so you have to make sure you look at the fuse chart on the top where you got the fuse clips from. Then I took the fuse out and put it back in 20 seconds later. When I turned my car on it did not fix the cel issue. The second time I took it out I cleaned my car and then put it back in. Either it takes a few times to take it out or it has to be out longer. Someone that has a tC I would give it 10-15minutes then put it back in. See if that fixes the problem the first time.

I think the post would be correct if the diagrams were left in the same place and only this change was made:
On the xB, the EFI fuse is #4:
On the xA, the EFI fuse is #12:
Otherwise, my xB has an xA fusebox ;-)

How did you know that you needed to reset the ECU even one time??
After I reset my ECU by pulling the #4 fuse, I just started up, warmed the engine for a mile, and then started winding it out in each gear at full throttle. To let the ECU educate itself about 93 octane, supposedly.
It accelerated so violently in 2nd I couldn't find the little tachometer in time to avoid 6000 rpm LOL.

When I added the K&N it would throw a CEL (check engine light) which also deactivates the VSC abd ABS. Because the K&N is oiled the oil gets on the MAF and causes the CEL. After about 5 resets and spraying electronic cleaner on the MAF sensor the CELs went away.
Anytime you add an engine, intake or exhaust perfromance part you should reset the ECU.

ive also heard that if you have your stock headers cat, to knock out a piece of the catalyst and put it between the 2 antifowlers, but sense i dont have the cat, would there be anything else that could work just as well as the catalyst?
