Message To peak at 23.1 PSI and it made less power then the steady 21.6..........The turbos seem to have a bit of backpressure....
He has a Blitz boost controller that I have found work great and is the same controller that is in Seb's car.
The controller was set at 84% duty cycle to get 21.6 psi on the PE turbos....I belive Seb needs to run a higher duty cycle to get that much boost.....For 25 PSI Seb runs 100% duty on the Blitz.
Going from 84 to 100 duty cycle on the PE car only changed the boost from 21.6 to 23.1.......Also the boost would surge over 21.6 and make the power go up and down....I am sure the backpressure was blowing the wategates open.
