So last night I took off my Injen uicp and inlet pipe and replaced it with the stock stuff. The car is quiet, pulls like a champ, psi jumped up by 2 and idles better. I realize maybe I had a boost leak but; anyone else had this issue or was I dealing with phantom knock?

Opinions appreciated.

 

It doesn't seem like a lot of people run that UICP around here. Why do you think you had phantom knock? Did you make any logs with the car?

 

if the stock is working better keep it on dont really see many gains from aftermarket uicp

 

They just look better than stock uicp. Also less bends on some aftermarket uicp. Too bad I can't put mine back since I cut one of my alum oem uicp pipe and coupler

 

i have the kit and no probs from my side

same boost, no changes.

on the piece from cooler up to where the battery is, theres a bracket - i used a rubber washed under it to mount it. just to have a tiny bit of flexi when i go over bumps.

 

Yea, logs indicated some knock from 2500k to 4000k, let it went away. I'm going to relog tonight and see what happens.


Good thinking , I think I'll do the same
