I experienced significantly higher boost levels with the TiAL and B&B header combination that before. My 1B spring set up in the TiAL was netting close to 1.3B. I actually moved down to a .8B spring and was still reaching 1.1B.
Right now I am running a .5B spring with a EBC (which I am still trying to get familiar with).
