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 installed my Stillen Z-tube last night so I really don't know yet but I will let you know later on today after work I'll check it out.

 

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

 

Spacer and exhaust then tune

 

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.

 

Battery negative performed ECU resets on automatics put the tranny in granny mode.

 

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 just got mine installed today as well and i dont even notice nothing yet.

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

 

Its all in your head man

 

Its just the sound doesn't do much.

 

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.
