Never under estimate a good tune. +19hp and 31tq
Last season with mods in my sig except a stock 78mm intake, 42# injectors, and stock rear with 3.73's after tuning I did 415/398 and ran 12.03@115.6 with a 1.76 60'. This winter I did a 35spline 9" rear with 4.11s and switched to a TPIS 90/90 intake and 60# injectors and scaled them but no other tuning. The car ran good and felt good but after losing 1.5mph in the quarter running an 11.96 with a 1.64 60' this spring I didn't know if the rear ate that much power or the tune was off or what. Went back to my local tuner to check it and baselined 403/357 -12hp and -41tq OUCH! Even though the seat of the pants felt good from 3-5k rpms it was pig rich! After literally 20 minutes and 5 pulls it laid down 422/388 now its +7hp and only -10tq from what I did with a 10bolt. Can't wait to hit the tracks again next week now!
