Something new I did over the weekend was instead of running my cut out. I made me a custom 3in exhaust single. Return my partial throttle and got on it a little. Sadly I didn't log it so I'll have to try to log it sometime. But too many traffic and night time is too many popo.

 

I dont know my injector duty cycle, but im sure its practically maxed out.

 

I say just take it to the tunner and have him try and control the boost with a good tune.

 

That maybe my best option right now. The next closet tuner to me is 4 hour drive. I can tow my car down but I don't wanna get turn around because my car won't hold boost. Another option is a e tune right now but I'm affair If the tuner can't look at my set up in person and see what's going on and why it's over boosting would be kinda hard to tune. Do you think a little exhaust leak from the down pipe would cause the creep? I have a small leak about 20 inches down on my pipe. No where close to my hot side.

 

This seems like something in your tune for sure. Where are you located?

 

Yeah this could very well be my tune. I'm located in coweta oklahoma

 

If you had 2 wastegates you probably wouldn't overboost.

 

If you switched to a manual boost controller, the wastegate checks out, then it's probably a tune issue. Your timing is probably extremely retarded

 

The manual didn't hold boost also. So with the timing retard too much the car will overboost?

 

It could. The combustion could still be happening through the manifold. A little bit similar to how anti-lag is set up.
