the SAE 1.24 means there is a 24% "correction" factor added to the #'s. if they did not give you one with a SAE of 1.0 i would go back and ask them to print that one. What are your mods
there was a bunch of wrx's and a couple evos that dynoed there a while back
my wrx, which is now dismantled and sold, dynoed at 250 hp, 255 tq uncorrected.
