So the first thing I did this morning was pull the Roto-Fab CAI off and headed down to Straightline Performance to get a baseline dyno pull 100% stock.
Results as follows :
390 RWHP/368 RWTQ on a Mustang dyno...not to shabby! There was a little dip in the TQ due to a little knock. Seems like the factory LS3 tune is fairly aggresive
