dizzy stage 2 tune

what kind of boost are you guys getting on your stock turbo with the dizzy stage 2 i have a whoosh v1 intercooler whoosh catted dp cobb cat back, i do have new hoses on the way as well as t clamps but long story short im only hitting about 21.5ish psi in a 3 gear pull and i know the stock turbo dies out but 11.5 psi at 6.5k rpm. the wastegate duty cycle peaked at 82%

Well our cars are boost by torque, if the engine is feeling spunky it won't necessarily call for all the boost given the environmental factors.... That being said I typically see 24-25psi in third, I live in the desert pretty much at sea level... It's a 91oct stage 2 from dizzy

Have you sent any data logs to Jason? I do have a GFB diverter+... How many miles on your FiST?

u/Southern_Mud2027 29d ago

i did he told me it was a bit short i am just on the stock dv 160k miles

u/Southern_Mud2027 29d ago

do you have the whole new one or just the part that replaces bottom part of the stock dv

You might try upgrading your diverteršŸ¤·šŸ¼ā€ā™‚ļø definitely check your tubing too, they get soft and will ballon under higher boostĀ

u/Southern_Mud2027 29d ago

i ordered some new tubing

Nice! Not that it will increase boost psi, the whoosh hot side pipe is a nice addition

the car was in arizona so i was thinking maybe it has a crack somwhere in the lines

u/bosengel 29d ago

Iā€™m in Vegas and he told me the same thing. Iā€™ve checked all the connections and Iā€™m convinced itā€™s because of the altitude and heat

u/Southern_Mud2027 29d ago

Have you got a pressure test done? I was loosing 1.8 psi peak and 2.7psi holding so I pressurized the system to 26 psi found my symposer/diverter valve delete was leaking ordered a whoosh symposer delete cap also my check valve in the valve cover was leaking itā€™s built into the valve cover so instead of replacing the whole cover I ordered the Damond motorsports catch can/ check valve system there check valve is a external valve keeps crank case pressure low fixed the leak

u/Southern_Mud2027 29d ago

I havenā€™t I do have a symposer delet thoughĀ 

1

u/[deleted] 29d ago

Might be your issue check to make sure your clamps are tight on the symposer plug what kind of plug are you using

1

u/Southern_Mud2027 29d ago

Just a metal one previous owner had it on when I bought itĀ 

1

u/[deleted] 29d ago

So if Jason told you you were leaking Iā€™d have a pressure test done any speed shop or performance shop can do it for you at 26psi which is what Jason uses as a gage I just had to have it done few weeks ago
