I took my car to the dyno on Saturday.Made 330whp/360wtq at 14-15 psi. I'm using the stock internal wastegate and a Greddy EBC. Problem is I couldn't get the boost to go over 14-15 psi and I still had a few clicks on the low setting on the EBC.
How high would your boost go before you added that NAPA throttle return spring? I think that's what I need to boost more than 15 psi.
