Donald - Jeremy (WR142LL) had the first remap that Williams did on the Sigma ECU and seems to be very happy with it. Jays also did the TB on his 4/4 Sport but I think you will find he said it wasn't worth it as it made it less manageable lower down & constantly had to be revved hard. I think he thought that going for the 4.1.1 axle would have been better money spent but perhaps he can confirm.
Pretty correct Roger. The best mod was the change to 4.1:1 diff....it transformed the use of 5th gear in particular and did nor funnily enough affect economy. I'd also fit a decent air filter set up like Cains, together with free flowing sports exhaust followed by a remap.
The throttle bodies sounded glorious but the performance increase does not justify the cost.
