Cheers Kanga. The engine is already running a Superchip (for a 2.5 V6)
and a Dastek Unichip in series which is mapped for the bigger displacement V6. Confusing or what!
I'd love to get it dyno'd before and after but it is quite a bit of extra expense for something I should be able to feel.. I'm thinking a de-cat pipe should cost me only £50 or so..
