Mi say they dun do mods at all... which i find kinda crappy...
thought all agents will do it as long as its legal.
i even ask if install Z-stab will affect warrenty, they never give
me a definate answer, just say better dun do it while its still in
warrenty
put amplifer in their own distributors, than warrenty still valid.
I think just for e battery... :<
