ya thats the plan now and back on the dyno i wish i could get the new turbo on before sunday last test&tune of the year anybody in wa have a 366xl?

 

you should step up to the largest exh a/r housing you can find for that turbo. .83 or .94 or whatever I am sure you will see a difference immediately with the tq not falling off. Unless you have the budget to get a whole new turbo then that might be your option you would rather take. I think a simple turbine housing swap will make a difference though.

 

^^That is a good point. If your budget doesn't allow for a new turbo, getting a larger turbine would "aide" the problem; however, its more of a bandaid than a solution IMO
