Hi,
I've had a 1999 Rover 220SDi for around 6 months now, and thought I'd investigate options for tuning it. It's got the 105bhp version of the L-series TDI unit (with the intercooler and the electronic Bosch VP37 fuel pump). Lots of chip/tuning box manufacturers claim upwards of
130bhp from fitting their product. The question I have is, has anyone had any experience of fitting any of these devices and what differences did they make? Also, are there any in particular that I should avoid?Thanks
Andy
