RE-Dynoed the gen 4 with BMW

[dennis1979gm]

I'm sure to get it up over 190 it would take a lot. They say with NHRA prostock cars it take about 10k per new HP. I think 185-187 is the wall on the gen4s after that its time to open up the check book! Lol

Bump- those are believable numbers

My past 08 w/ PC-V & custom dyno tune, link-pipe & slip-on made 167. My stock 2011 feels just as strong as the 08 did. I added a link-pipe to my 2011 and it filled in some mid range power but it didn't seem to add much on top. The stock system just doesn't seem to be very restrictive so I have no doubt the flashed ECU could have added 15 to 20 hp.

More than enough for the streets.

What scale was the Dyno man using? SAE or STD

Nice numbers. I'm impressed how much the re-flash helps.

Weird but my bike with filter pcv and slip on got 177. A friends BMW got 181 on the same dyno and the same day. She only had a exhaust mod. Not sure which one. This is in Australia so not sure if there's any difference between us and u guys. The ten absolutely blitzed it after 9k revs,, torque was bout the same overall. Good on you
