A few days ago i got my power blocks installed and tuned while running e85. heres a dyno sheet.
Installing the power blocks on an existing tune lost us about 10hp. after a retune we were able to get the power back up and make some good gains. While the dyno didnt say much in terms of big power, taking the car out on the road for the first time with the blocks installed told a different story. Car felt more responsive even on the bottom end and you can feel the gains from 5000-6500rpm. It felt like i gained more power than what the dyno suggested. Power does fall off a little after 7000 rpm thats okay with me. all in all i am happy i got the part installed and i love how the car responds now.
in case anyone was wondering, i dont remember the exact numbers of what the dyno numbers are but i believe the finals numbers after tune/catlessfrontpipe/blocks was 187hp and 168tq corrected.
