those cars are reliable, gas &? good at handling... I know Toyota's are 101% trustable on reliablity.....but just asking....If i want to add more speed to it is it a good idea 2 put a computer chip and throw throw in a KM performance air filter, and put some STP octane booster in the tank..... Can i beat a Mustang, Charger, Corvette & car's like those.....with the Supra
