Pretty sure the blocked re-circ valve pipe is causing your juice problem. Or both, there there for a reason!! Could be over compensating by not having the air dumped back into the inlet, doesn't know what/how much to measure to get the air fuel correct.

A de-cat does increase consumption but not by bucket loads i recks, got one on mine and it's not bad when driving sensiblyish.........

WTF is budgies:screwy: :screwy: - turbo flutter sound you get on rally cars yeh???

Thought it was it does sound good!! Though it could be damaging parts that are under stress and costing you a fortune at Mr Shell.:D

Yeh back to normal, best way to go for reliable/ not as costly running!!
