Basically, Finished buying my Zisco ram horn TD04. My setup will be; Zisco Ramhorn Manifold Decat TD04 Turbosmart/TIAL 38mm Wastegate (0.6bar spring) FMIC No BOV HKS Hi Power Would this setup be able to run at 0.6bar on the wastegate without mapping? Basically, I'm inpatient as fook. So i'd like to slap this on over my holiday over xmas. I haven't got a SAARD FPR or Wideband yet, but since im runing below factory fuel cut i think it would be ok? Then Febauary, im planing to have it mapped on E-Manage Blue/Ultimate. Opinions,Feedback or advice would be great.
