You should probably slow down and consider the company you're in here.
And just for clarification, it's not a slam on your driving skill --OR-- the possible lack thereof. It's a general observation for ANYONE with a limited amount of track time. The only reali similarity between street and track driving is that the steering wheel, shifter, gas, clutch, and brake pedals, are in the same location that they were in the last time you drove to Walmart.
If you believe that you have no room for track driving improvements then you may as well not ever mod anything because adding more power will likely make your times progressively worse.
