I have known Thomas and Mike for a few years now, did business with them and used to work with them on a commercial basis. These guys are the epitome of "diesel nerds" and know their stuff about diesels and gassers in general.
I have let them work on my jeep in the past and they did it right and did it for a more then fair price and I didn't even get a homie hook-up. If I quit being lazy and putting things off, I will let them work on my jeep again as it needs some attention but im too busy buying toys...
Anyway, these dudes are super legit and you would be a fool to take your truck to any other diesel shop in the valley who over charges because of their name BUT you can always bring your truck to OSTS when it breaks from the other shops....wouldn't be the first time...*wink*
