looks good i would get the rr one just for the computer stuff
but i have no experince with it i havent raced or really wanted to since i got rid of my old truck
and since am only getting maby 90-100 hp outa my car its not worth it for me
if you have the money get it if it turns out you don't like it
sell it on ebay make up some story its an svt guage or something like that
