I had the last used one from james sherlock, he asked "whats going on ? everyones been buying them, there's been a bit a rush on these the last couple of days" .
Had mine in since Friday, only done a few small trips, bigger one tomorrow to see if it cures the running issues I've had, kind of on a sale or return basis, so if it is OK I guess I owe SPC big bucks for fitting it, if not back to the drawing board to find the fault.....not looking forward to the bill though...
