Does your car have tire slippage at launch?
Also, when you said 7000 rpm pill, a light went on. Sometimes those will start before 7000, costing you mph. This car sounds like it has more in it by a fair aqmount. Try at least a 7200 pill, and lower your launch rpm to 3200 for starters to see just what happens.
