I'm thinking about purchasing a Turbonetics Deltagate mark 2 from a guy I know. It has a small round sticker with the # 5 in red on top. Is this number an indicator of the stiffness of the spring inside. The guy claims that it opens up at about 9 psi of boost. Can anyone tell me if this is correct? I don't wanna shell out the cash and end up with the wrong WG. Thanks.

 

Don't buy that wastegate. It is the shittiest wastegate around. The boost spikes are terrible with it and it is just an all around poorly designed wastegate. save up the money and buy a quality Tial. The headaches you save will be worth the extra money you spent.

Deltagate = worst wastegate ever made

 

There have been people saying they've had bad experiences with it and then there are some who report no problems with it... but as Whitney said if you got the extra dough go the extra mile.
