Lol i wish I was back home I'm SoCal.

I'm good tho thanks like I said I just got my REVup box so I'll just keep it for now.

But as far is my setup right with there ztube and REVup airbox?

Yes

I got the same exact package from eBay and installed it yesterday. I noticed a substantial difference in performance and sound. The engine climbs rpm's much quicker and the throttle response is faster also. In addition, the car is overall faster. Im assuming I gained at least 10hp. My old intake filter was pretty dirty, so maybe that's why I noticed such an improvement. Whatever the case may be, intakes do improve your performance if they are made out of the right material and housed properly. I am very satisfied with my $225 purchase. If anyone is considering buying an intake for your G, I would highly recommend this set up.

I would agree with the rpm climb. I have noticed that the rpm would kick up a lot more quicker then before. My old filter was pretty flithy too. It does seem to be a little quicker then before which I have been noticing lately.
I might try the stillen down the road.
I haven't really noticed any sound difference but I plan on getting ISO plenum spacers soon

Did you use any of the old rubber cuffs for the install?

The stillen is lower quality then the tube...

I can PROMISE you, you did not gain 10hp lol.
+1 on better throttle response due to the dirt. Your throttle body may be pretty dirty also.

Lmao!! 10hp

Wouldn't happen to have that rev up box laying around and want to sell it would you?

I read that when installing the ztube to do an ecu reset/ foot pedal reset. What does that do and is it necessary

Just log your radio channels, and pull the battery negative cable off the battery. While it's off, pump the brakes (I think) to kill all built up power and it will essentially reset the ECU. then place it back on. Do you notice a difference?

What's the purpose of doing it tho? Is it suppose to make a difference

Modern ECU's learn from their environment and it will affect the tune on the car. Resetting the ECU puts it back to it's original tune and beings the learning process from a fresh start. Things like temperatures, air density, air flow, fuel octane, etc, will affect the learned fuel trims and spark timing. It's not necessary to reset the computer, as it will eventually learn from it's new environment, resetting it just helps speed up the process.

I installed a oem 350z tube also didnt notice any difference in sound. I installed a new exhaust a day earlier. My mid pipe is Custom no resonater sounds great. Butt dyno says gained a few ponies and better response from the pedal too!

your probably right, although she does seem to be a lil quicker.

I installed a rev-up airbox this weekend along with oem Z-tube. I switched from a stillen intake and stock g-tube. I reset the ecu after install. I felt like I put a plastic bag over the airbox. It just didn't seem as peppy or Rev happy as with the stillen airbox. The mean sound was also gone, it sounded like stock and throttle response felt like stock. I was using wix paper air filter in the Rev up airbox. Next I switched back to the stillen intake and kept the oem Z-tube. This combo felt the best to me. The stillen intake sounds along with Z-tube, both amplify to a deep mean roar which I love and it also kept the excellent throttle response and is Rev happy. This setup is a keeper for me.

If anyone wants a brand new revup airbox, pm me lol or check out classifieds later when I post it
