i was thinking about going with the reflash b/c it is way cheaper and that is pretty much all i am going to do. i have all the basic mods of i/h/e/tp. and so i would get the toda reflash just for a 8500 redline and 4200 vtec. the kpro souds very nice to have. but i am not going to be a mod head and plus i dont have the cash for one. i would definitely get it if i were to do a little more but the reflash sounds like what i would do anyways.
