I had Maximum do the Ecutek in my car. Everything else is still stock. No problems so far. Performance-wise, very noticeable difference. That "throw ya back in the seat" feel comes on earlier.
It was suggested I may notice slightly better fuel economy when driving "sensibly," but I am yet to see the evidence...
So, you guys recommend STechnic for servicing/maintenance/brakes etc? I've only heard of them recently and have been thinking of shopping around...
