So for 100 extra hp and 130 lbs of torque I shaved .3312 off the qtr mile and picked up 1.95 mph.
It looks like your car is still down on power for some reason. Have you checked your air filters? Are you running 93 Octane?
You can also put your 1/8th times into one of these calculators to get a 0-60 estimate.
