I've been hearing that part throttle sucks ***. Say I were to run a ITB setup on a TE tuned ECU, I hear it would run like crap unless I was WOT.

 

not true...hell my roommates car with ITBs seems to run better during street driving than my car does...

 

You need some type of vac log, or else it will run like a huge POS

 

yup

 

Whats a Vac log?

 

Haha, nice avatar. A vacuum log is just a small chamber with a few different vacuum ports exiting/entering. Basically when running ITB's your eliminating the intake plenum where all your vacuum lines usually connect to. So, your going to need another way to route these lines to supply your brake booster, MAP sensor, etc. with a vacuum source. Thats why we need to use a vacuum log.

 

Excelent answer, thanks a lot, i understand fully now
