Here is a 2013 Camaro SS 6.2L LS3 6spd car that is pretty stock.  Just a cold air intake installed.  I always recommend before you start making big changes to go get a baseline dyno pull as all dyno’s read a little different and I know the one I use typically pulls 10% less numbers than most other dyno’s.  But by making this base pull now and then hopefully we will see this car again after long tube header install and then who knows and we can post those increases as it progresses.  While the car was on the dyno, I mainly changed the air fuel ratio to get the best dyno numbers.  Timing chainges didn’t have much postive affect.  I only changed the timing curve a little.
