I get mixed "seat of the pants" performance feelings on the improvement on my 2015 F3's. It's been a cold winter in Ohio thus I'm just recalling my performance from fall 2017. Today the tem was 46 degrees--sun was shining, no wind. I went out to my only close freeway & hit 118 mph in 6th gear before traffic slowed me down. It felt like it was still climbing but I didn't want to park in the bed of the semi-trailer in front of me.
45 degrees --great performance in each gear versus the fall 75 degrees temp--performance didn't impress me. Reminded me of the old drag races when we put ice cubes inside the air filter container.
