I was telling a friend of mine about getting my PSC1 installed soon and he brought up a good point. What will this do to a factory warranty?? I have the extended 7 year 100K that I paid good money for that I dont' want to void. I called my cousin who is a Yota Salesman and sold me my truck and he said maybe if the motor blew and they traced it to the PSC being the reason they wouldnt cover that. But he said if like the power steering pump died they wouldn't question that if you had fuel mods. Basically he said any alterations you do to a truck can void the warranty but it sounds like that is VERY open to interpertation and has alot of grey area. If that was the case then the lift that the dealer installed on my truck when it had 14 miles on it could technically void the warranty. What do you guys think..?.anybody have any horror experiences with warranty stuff? I'm thinking it's not going to be an issue but some reassurance would be nice. :thinking:
