I am still running sequential, when i go on wot, i get a a lot of turbo lag. Once it hits 10 psi it goes down to about 5 then it goes back to ten. I think that the primary turbo is messed up. Usually on fifth gear boost goes up to about 12 psi. What do you guys think it is? I already checked the troubleshooting but i can't find anything.

 

Turn up the gain on your boost controller
