Here's my tune results. Installed my Eurocharged tune. My car is a stock 2005 Limited Roadster. Here's my initial results using the Torque app with a blue tooth OBDII reader. Zero to 60 about 2/10 of a second faster (7.0 vs 7.2), 1/4 mile speed 10 miles per hour faster at the end ( 67.4 mph vs 57.8) , HP about a 14 HP (344 vs 330) increase at about 600rpm lower than the previous test without the tune. The car definitely feels peppier. I'm sure if I had some mods installed I would get more out of the tune.
