Did the second round dyno with the only item changed was the air filter in trying to figure out this lack of what was suppose to be a decent HP gain. Well Nope, seems as though in the swap I netted 1.5 more Hp and 1.3lbs torque with the Pipercross. With the KN in it went down too 109. where with the piper we saw 111+, one 112hp run.. Go figure. All though there was a little room for fine tuning the fuel map, not really a lot of wiggle room for the trouble today. Ah, But, Mike was hoping to have had new upgraded software program loaded up and running by today, which didn't happen, so wants me to come back to try the new software on for size seeing what results we get. but as it stands now, Piper-cross wins the comparison. Still nothing close to the last dyno that was done last year.
