ive heard of many different problems about the itbs not opening up full throttle..

anyone have this issue?

 

I reused my old throttle cable (LS)...Only problem that I have with the itb's is that it doesn't fully close after I release the pedal...kinda sticking, so we just put an extra return spring. It opens up just fine.

 

yea i just started to have this problem with my fully built b16 itb set up. I'm running the twm ones. i was running my stock b16 cable until i call up twm and they told me that i need to run the gs-r cable. still the same **** after swap cables..still doesn't open full throttle..anyone with help i appreciate.

 

I just installed some TWM ITB's on my LS-V and having the same problem. Im going to wire up my TPS tomorrow and see what that reads when I press the pedal to the floor. Anyone come up with an answer?

 

there is a thing on the bacc of the pedal and you gotta cut that off. after you cut that off you can start adjusting the cable wire so it can full throttle. lmk if this works. cuz it work for me.

 

are you talking about the bushing on the back? (pedal side)
