even if you saw, 3-5hp, & got a crisper throttle response, & maybe a touch more mid range I personally would be happy with that for £50......... I'd much rather spend £50 with someone that was honest about the product & gave realistic gains & pros to using that chip, much like the ebay chip for the 16v that was mentioned a while ago, than spend £250-300 to someone saying 18-25bhp gain, which we all know is bull anyways...
