Boost Check.

Did a final bit of experimentation with the boost set up on my way to the RR today, bit of history, i used to have low boost problems so checked the whole system but could not find a fault, so switched to TTC mode which i liked, but still low boost, so i messed around with re routing the boost/vac piping and managed to get 1.2-1.3 BAR by just connecting the the EGBV and the waste gate together no VSVs, but changed it back to normal TTC as in the cold weather it boosted to 1.4:(

now my final check which i tried today was to cut and block each end of the pipe that goes between the waste gate actuator and the waste gate actuator VSV, as you would when a boost controller is fitted, and what did i get .5-.6 BAR, so it looks like a controller will be just what i need.
