Well, I took my car in after driving around with 93 Octane for a month. And Chris from Excessive got me 6 more RWHP and 8 more RWTQ!!!! This is my baseline before I put on duals. I want to know once and for all if duals have a performance advantage. So, STD numbers: RWHP: 211 (from 205) RWTQ: 245 (from 237) SAE numbers (using a 2.8% difference, as I don't have the original SAE #'s but got them this time.) RWHP: 205 (from an estimated 199) RWTQ: 239 (from an estimated 232) Both SAE and STD are corrected numbers. SAE corrects for an estimated 77F and STD for 59F.
