Yes I have had one and it was quite good, problem was just that ‘it’s quite good’
I have also put a tuning kit in a 99 and a home tune in another.. both shot just as well as the Imp, same power, lack of twang and a smooth and consistent shot string over the chrono
I know Sandwell get some great reviews, Si Pittaway being the obvious fan boy but personally I fail to see them as anything other than a good home tune
Just my opinion of course
