yeah, i guess the CR is 8.5:1 so that is a little better. No I am not going to be running 15 pounds daily. Yeah this is going to be my daily driver and will probably just run like 8 PSI to putt around town in. I drive my cars very nice and dont run the shit out of them. might turn it up to 14 pounds or so on race gas but we'll just have to wait and see. But the computer system is the ZDYNE Gold Computer. I have been playing with it and it seems like a fairly easy system to run. I am okay at tuning but I work at a performance shop and my manager is VERY good with tuning. But it should be a fun little car. It is makes 250 to the wheels I'll be happy. Well, i'll let ya guys know. take it easy.
