I will be taking my hybrid down to PIR on Friday. I will not be able to go to the dyno tune so I will hit the track. Its my first time out with this car so I should see 13s I would guess on street tires. I am at 3160 lbs and 1/4 tank of gas. I think I am going to put in a bottle of injector cleaner in my next fill up too for the track.
