was a true bolt on swap, boost control lines not touched. i run a tial 44mm extrernal gate. and yeah when time permits we might try putting a degree of timing in around the midrange to help it.
let me just say this tho... with a super responsive set up and such a large wack of torque in the midrange. traction is very difficult. i believe for circuit stuff you wouldnt want this type of arrangement. you'd want to opt for a larger rear and lazier ramp to prevent wheelspin.
