Hey Forum - Do any of yall have results from running your L83 on a dyno?  I plan on doing a Black Bear tune soon and was going to do before/after dyno results.  Curious if anyone has results to post here that I can compare to.

 

My truck is a 2014 LTZ Z71 with the 5.3L and 3.73 gears (9.5in rear end) from the Max Trailer Tow package.  I have a K&N CAI and a custom dual exhaust where the muffler and resonator were deleted.

 

FYI: I was reading this thread earlier.  My truck is currently governed at the stock limit of 100mph.  So, I assume it would still be safe to take on the dyno.
