I love those guys at Allisport.
Took my car up there today - I'd been playing with the fuelling and managed to get a bit more kick out of it myself.
They take it out, raise the boost 1PSI from where I'd had it, tweak the fuelling a little and now damned if the thing won't wheelspin.
Their magic touch has done wonders for the across-the-range torque.
I've now got a 200TDI Disco that performs better than my old TD5 did and within a whisker of a good few V8s I've met. It loses it a bit at the top end, but to be honest I don't want to take this car over 90MPH if I can avoid it anyway.
