How many miles you trap at the end?
Two things are happening:
1. You need more time to know better the car
2. The car need a tune ASAP
To check if everything is fine take it to a dyno, it should be around 190whp right now. I think that something is wrong with that car.
For the Wheel Hop a good kit of Motor Mounts and a Torque Damper will help you a lot in reducing that axle/trans breaker problem.
I manage to do 14.5@98mph, 2.33s 60ft with stock tires, CAI, DCRH, Pulley Kit and exhaust open in my SI. With a good tire setup I'm sure that I can shave a few more tenths to the low 14's.
