I just upgrade my TII's turbo to a kinghtsport turbo. I discovered the turbo cann't pass 0.5 bar even though I have a Profec B. It worse than stock turbo. I checked all the stuffs and all here. Should I get a larger injectors for this turbo or my boost controller have problem. Anyone experience this? Thanks

 

i have no experience...but my guess would be that it is a boost controller issue..7lbs. of boost for a aftermarket turbo does nto sound right..are u using the stock turbo manifold? check your vacuum lines to the wastegate and your boost controller.

 

disconnect the boost controler and run it.. see what it boosts to then its its 7psi stock area then try a manual one and see what happens

 

Yes, I am using the stock turbo manifold, I will try again ane post any changes. Thanks

 

remember 7 psi on a bigger compressor is more than 7psi on a stock comp side.
