Re: Just finished HM Itb's need help
Is their a vacuum problem with itb's? My fuel pressure was a bit high I took the vacuum line off to adjust it and the idle never changed. It didnt feel like their was any suction.

whichever you aren't using, I suggest you tap them with a barb fitting and feed those 4 lines to a vacuum log. That will help you feed your brake booster and give you a good place to tap in your FPR and such.

You built, installed, and used these things without understanding what your getting into? 
What set of ITB's are you using? If you mounted your own TPS it could be in need of adjustment. Your going to need to use a voltmeter to get it dialed in and that can be quite a PITA. If your running the CBR throttlebodies with the TPS thats similar to the Honda (our cars) TPS, you need to reverse the two outer wires because the ITB TPS operates in reverse to the cars TPS. You'll basically have to switch the two outer wires to match the way the TPS would be set up if you were running a DPFI setup. That could be a good reason your running so rich.
