I just want to thank Steve and Dave in Australia . Thanks from a grateful Pom . I took the plunge and ordered and fitted the Racechip GTS 5 today. The car is truly transformed it really is. I was happy ish with it before but now it’s a much better proposition. I am not a number chaser I will leave that to others, but in terms of drivability and outright performance this option is excellent. I considered the Burger option but the import tax was so high it really didn’t make a lot of sense which is a shame. Very happy with the Race chip option. Cheers for the advice guys and apologies for opening a rabbit hole of differing opinions
