The R8 is no slouch, but it will depend on how your car re-acts to the generic tunes supplied in your box. Before anything else, take you car to a dyno to get your AFR's checked for each tune. Also re-gap your plugs for the 10PSI tune. If you have 240RWKW then you will have fun with R8. You;re in an auto so you can stall it up an be gone by the time he thinks about snatching 2nd.
