Z Tube= Power loss.

I installed a Z tube (reset ecu) and noticed the big difference in sound and a noticeable difference when I punch it at about 65-70. On the other hand my car no longer jumps when I punch it at about 25-30. Seems like it doesn't drop down a gear and go like it used to.

I switched it back to OEM tube (reset ecu again) and it gained my jump but lost the pull at 65-70.

Does anybody know how I can keep my Z tube on and get back that low end jump? Thanks for your help.

I am sure you will get the same results. I am sure someone on here knows how to compensate for the loss.

The Shifting points of the automatic do not magically change when you install a intake tube.

it just in your head. Plus you did a reset on the ecu, now your car has to re-adjust to driving style.

I wouldn't imagine it would change but it doesn't down shift and take off like it did with the OEM tube. I DID unplug the battery when I put the Ztube in but I did the gas pedal reset when I put the Ztube back on. Same results. I swapped them out a couple of times with the same results.

I thought it was in my head too but after swapping them out.. I decided to see what you all thought. Looks like I will have to start shifting manually.

i think with ecu reset, you gotta put on some miles before the ecu get optimal...plus it's a z-tube..with 1,200+ posts, i think you should know enough about intakes gains to not let this get to your head.

Yep, I did my searches with nothing conclusive. I wasn't sure if anyone else had this problem and if there was a simple remedy for it.

I dyno compared the Z tube against the stock tube and it made no difference.

I thought the stillen intake w/ Ztube is just for that growl in that engine and no restrictive areas

Didn't really notice that much of a difference when I got mine, and wasn't expecting to. I just loved that growl when paired with the pop charger lol.

Your pretty much just changing the intake note.
