I've been recommended the A/S inlet and the power I want will be possible on a 63mm piped cooler and 70mm core so good to have it confirmed Caddyshack thank you. I do need to find a suitable large injecter for 550BHP Max but mappable on L8, I've had in confirmed it is possible to reduce boost at set revs using L8 if traction is constantly an issue at certain RPM, good to know, only a few tuners will map this though so Harvey Gibbs or Stu at MSD will be given a call in the future.
