I am tuning my car this weekend on my new setup(went from twin to gt40r). install a s@#tload of parts. boost controller,complete fuel setup, AI, gt40r, full inch SS exhaust and probably more I am forgetting. I was wondering what people are using for duty cycle at what psi. I have never used this controller before and would like to have an idea where to start.

thanks

 

Depends on a lot of things, firstly would be the wastegate spring pressure. If its a 20lb spring you won't want much....

I started very low, around 10 and went up from there. Just have to play with it.

 

12psi spring. (I think)
