Started installing my used HKS boost controller on my 91 turbo2.

I'm planing to use the same hoses as the boost controll duty valve is useseing .. is that bad ? they are a bit small .. i will boost max .8 or less ..

i took the "boost preasue" from the vacum line that goes to the original preasure sencor ...

Also, can i dissconnect the original duty valve without getting any errors due to that ?

When I disconnected my stock controller it gave me a check engine light.

Aftermarket EBC's are plumbed differently to the stock one. It should come with the hose you need. Remove the stock hoses and run two new hoses from the new solenoid, one to the wastegate and one to the turbo. This should all be covered in the instructions.
