They don't usually tune for the wheel.

If you can cram more air in there without going overboard, you can make more power.

 

I hear yah. I just wish we could see a dyno run from the average Joe who decided to try it out... no ability for adjustment for tuning. If I were able to dyno for free I would buy one and give it a shot, but dyno runs are not cheap here locally.

 

FYI I still have not seen anything on the net regarding one of these put in a OBS turbo... they all show SD turbos... and claim some pretty big numbers...just thought it was interesting they still have posted anything on a OBS turbo...however they posted an OBS with a SD turbo in it... then removed the video..

 

It's hype and BS.
