k srry for all the posts but got the sound to work, freekin awsome sound actually bounces like a b18, but ya it literally is put the ADDON folder(not the contents, the whole folder) to the MAIN SLRR folder, so addon folder is above cars,data,decals,etc., set limiter to 000 or 500 for it to work(eg.9000 or 9500) and sound runs out at 10500rpm, took me awhile to figure out but hope this post helps ppl
