Atr Wastegaste Questions Need Help

[BLACK DEATH DSR]

I need help on how to setup the ATR external wastegate so I can get the boost around 25#s. I also have an ATR needle valve setup too, that is closed all the time. Right now I am getting around 14#s of boost at WOT. Do you use a lighter spring and then open the needle valve or do you use the heavier spring and use the needle valve to get the boost higher? Which spring is which also? I have about 4 of them that came with the car when I bought it? I am getting the car ready for kill mode when I race this Mustang with a 300 shot. It is fast so I need some help and I will be using C-16 in the car.

I guess no-one knows. I even emailed ATR and no responce from them, they suck.

open the needle valve to get more boost or crank the set screw down on the wastegate.

The stock ATR spring is notoriously weak. I believe it may be 14lb but don't hold me to that. You want a stronger spring to hold the wastegate puck closed.

the gold/yellow spring is rated for 16-18psi. with the bleeder valve closed you should be around that boost level, open the valve and the boost should rise. if youre only getting 14psi, you probably have a vacum leak some where or youre gate needs some repairing, check the diaphram.
