Mine didn't come on after installing my Z tube and pop charger, if that helps any.

 

should i unplug my battery just incase? or do i not need to worry about that?

 

It's always safe to unplug the battery just "incase" IMO.

And reset the ECU after the install.

 

I got the berk ztube and put in a new k&n and its noticeably louder to me at WOT.
It didnt really change the intake sound but more like magnified it...

 

Due to the shorter intake runner design (ie intake manifold) of your car's "revup" motor, the induction noise change of the Z-tube isn't going to be as obvious as those of us with the longer intake runner non-Revup motors found in all 03-07 automatics and 03-04 6MTs. If you went with the MREV setup from Motordyne, you'd notice a bit more induction noise because it uses the longer runner design.

 

remove the power duct cover and the intake will sound even better

 

Whats the power duct cover?

 

^the removal cover where the intake box has the opening

 

While increasing heatsoak and the temperature of the air going into the engine.

 

+1

don't remove the power duct

 

^nothing to lose sleep over imo. u think those with pop charger doesnt suffer from heat soak?

 

jwt pop charger has heat soak bad. which is why i got rid of that heat shield and got a stillen air box to go with the pop charger filter (its much better design than the stillen filter, IMO)

 

^thats another thing i never understood. why replace the oem airbox with another airbox that looks and functions the same? besides the fact that now u have a cone filter in there instead of a panel filter.

 

well i have a Ztube apexi combo and i can really hear the sound change around 4-5k rpm's over my all oem setup

 

I noticed that you have no bracket holding the z tube in place, is that ok? the z tube that i bought didnt come with any brackets.
