Dude you look more the fool than Shane or anybody else. Jumping all over every ecu thread to spruke Vipec/link gets old very quickly. As for marks tuning, Maybe if you lived up here among the import community you would not be so closed minded.
Obviously mark can tune a big hp car, so can any other tuner given the opportunity. but like all tuning shops there are as many "unhappy storys" come from Marks workshop as any other.
To my mind Tuning a big hp car to run for a few seconds would not represent the challenge involved in tuning a car like mine. 500 hp that gets daily driven, tracked, dragged and used in general. I want a car that will cold start, give good economy on cruise, track in a qld summer without pinging its head off and generally behave itself. No doubt mark can do those things but over 1000 hp would not be the credentials I look for when picking a tuner.
I swear by my tuner but I know and respect others who wont use him simply because of their experience. He gives me
what I ask for and you cant do better than that.
Take this as a mark bash if you will but it isnt. I am simply saying he isnt God when it comes to rb tuning. just another of many who happens to own a helluva quick drag car and can be as fallible or infallible as the next guy.
p.s. I use a haltec E11v2 and couldnt be happier.
