On pump gas(94octane) i put down 451whp and 390ftlbs at 22lbs of boost on Slowboy racings Dynapack. I then went to Buschur Racing because he had the Apexi power accel software for my power fc so i knew i could get a better tune. Keep this in mind I bought the L-jetro power fc which retains the maf sensor. Dont ask me why i did this, too much pot over the years kept me from reading to see they made the d-jetro which gets rid of the maf. I baselined with SBrs tune at 312whp 286 ftlbs at 21.5 lbs of boost on pump on buschurs mustang. Note that it was 95 degrees outside with crazy humidity levels. When dave was done I ended up at 340whp -302ftlbs at 23 lbs of boost. So I gained an extra 27whp-16ftlbs with daves tune. The car had more than that dave told me but was held back by the maf. He said with an aem ems(which i just picked up) I could have got an extra 20-25whp which is very true. My friend has the same setup mod for mod other then hes running HKS272/272, im doing HKS264/272 he also used the AEM EMS. On perfect weather cond last friday(low 50 degrees/no humidity) he went to buschurs and put down 380whp-306ftlbs on 93octane-22lbs of boost. On 104octane he put down 426whp-336ftlbs-26lbs of boost using the same map as his pump gas just turning up the boost on buschurs mustang. Hes going back up to get a real race gas tune shortly. So I know my car can make ard 380whp on buschurs with SBRs kit on pump give or take a few whp with the AEM EMS and better weather cond.
