Ok I know is not the new clutch that was install but after the clutch install and 150+ breaking mile. It seems like on full throttle when the secondary turbo begin to boost the lower the gear the more hestitation. Like on 1st when the secod turbo begin to boost 10psi then it hestitate then the boost decline and stay at 6psi.

Please need some advice!!! OOh it drive and idle fine but when to floor it the primary turbo boost good but when it goes to the secondary it hestitated.

 

Please help!

 

So you are only seeing 6 PSI after transition?

What other work was done to the car besides a new clutch?

 

just the clutch. I toke the manifold off and check all the hoses and it look fine but when I take the air control valve it was black like carbon build up. Should I go non-sequental?

 

If you dont have any other mods to the car besides a clutch then non-seq most likely isnt for you. In order to get the most out of non-seq you would need a full exhaust, intake, etc...

 

If you pulled off the upper intake manifold, it sounds like you miss routed a vacuum line in the install process.

Recheck the vacuum lines, especially the two on the firewall side of the UIM. I miss routed those once basiscally had no secondary boost.
