ok cut a long story short, have recently just installed a KKR430 on my car, now we have been having a few problems with the KKR430 just not been up to scratch, so it's getting sent back for a new one, now they have asked me if i would like to go up to the 480 ? just wondering pro/cons with going to the 480, it will be on a R34 neo, any help would be great thanks
