Yo peeps, I have no idea wat is the cuase of the boost creep. It has never creeped more than .5 above the original amount of boost. I recently installed an elbow to my manifold and the only thing I can assume is that that could be reason of leaks but how? Anyway, I have an AVC-R and on it it has an option of feedback speed setting but I don't no if I need to increase the number or decrease it? Also, I know I have it set for learning gears so shouldn't that prevent me from over boosting and will this option automatically fix my manual settings? And there is another setting called the duty cylce. What is that and can I use that to help me from boost creeping??

 

What kind of manifold are you running? The elbow might be too restrictive as well. Is it crushed bend or mandrel bend?

 

It's a rev hard manifold with a bent I got from Ben at importparts which was suppose to be made for rev hard manifold (i believe). One thing I have notice is that the elbow is a little smaller (fitting on top of the manifold) but the bolts line up perfectly and I did use a paper insert (in between the manifold and elbow).

 

 

Boost creep is usually a problem due to a wastegate too small the complete the task of boost controll. In my experience a lot of internal wastagates creep because they are very ineffective for high hp applications. If you are using an external. but making tons of HP be sure you have the correct size Wastegate for that HP.
