I drive an 800 hp Z06 corvette when I do a track day. Last year I drove a 790 hp 2011 Camaro at the track. So even though the stock ZL1 has a lot of hp, the car does not perform as well as it could. Lingengelter's price on their package is $4895.00. If the price is too high you should talk to them. A number of ZL1 owners have upgraded to this package and appreciate the increase in performance.
My ZL1 is very unique and has recieved a lot of attention and great comments throuout the summer when I showed it at different car shows. I even won a driver choice award at one. I build a lot of unique and beatiful cars that also perform well. I am always trying to create a car that looks grat, and performs even better than it looks. here is a picture of the custom interior:
