Re: K6 600 Bogging under heavy throttle/higher RPM
Did you run the fuel flow test as described by the manual? For 30 seconds? And what was the fuel amount?
As Tate said, a full exhaust most definitely needs a tune using either an ECU flash or a fuel module. However, you talking about the servo sounds like it has just a slip-on. And the valve is to be fully counter-clockwise to be open.
If it's bogging at high RPM, no amount of TB syncing is going to fix that. That's a big issue, and you need to test it. If it's not the pump, it is quite possible that a fuel injector is not spraying, spark plugs need to be replaced, vacuum leak, low compression, etc.
