    Been awhile since been on here. Wanted to share that I finally got the motor professionally tuned by Xact Dyno in Phoenix. Made 289.6whp/260tq on pump 91. The numbers honestly disappointed me (was hoping for 300whp). The tuner blamed the cat for being too restrictive and I also found out later that the clutch was slipping. 91 octane also severely affected the timing on the top end.

    So, shortly after that dyno I installed a higher flowing (200 cell) cat, new clutch masters stage 4 clutch (upgrade from stage 3), AEM e85 compatible fuel pump and a flex fuel sensor. The car is currently on a blend of around E60-65. Eventually I'll be getting it re-tuned on e85. Until then here's the dyno clip:
