yeah, it might as well be that, but he says its cracked but fine. i am still saying it could be the fcd.

 

There is no sudden change at 6000rpms other than boost falling off. The engine is smooth and is firing on both rotors at the high rpms. As I said, with the wideband we can see that fuel is not a problem.

Some of the guys on nopistons.com are saying the turbo is just to small with the intake being ported, and its common for it to drop down like that. Who knows, The T-76 w/ a 50mm Gateis going on shortly

 

try and do tell of said results.
