Dieselogic was a great place to deal with, the person was nice, the thing I really liked was I'm a do it yourself guy and a lot of the times when you call and ask questions people want to make you feel stupid for the questions you asked and don't want to deal with you but Dieselogic wasn't like that. they were very helpful and got me the kit I was looking for at a good price.
