Ed at Fusion Motorsport down in Surrey. very knowledgeable & experienced tuning wizard
back in 2009 he fitted Nistune onto my 1993 1.3 slx with NATS and dyno tuned it at Surrey Rolling road which was nearby.
he later remapped my car in 2011 when it was turboed.
Thanks PollyP, saw the link to Fusion on the K11 side. I remember him being a K10/K11 specialist. Have just checked his website, says he has shut up the unit permanently, but doing other stuff.
