hypertech are NOT good from what i heard, heard that the main thing they do is chuck the knock warning level on the PFC from 60 to 80 and do a rough tune and charge the earth for it, i havent been there so cannot confirm this, what i can confirm is that gerald/nige at ice are 110% genuine and great blokes and do fantastic work, i was sitting with nigel the whole time he was doing my powerfc and i still havent required a re-tune and i can fang it whenever i want (within reason, of course on boiling hot days you cannot but meh, thats got nothin to do wit tuner )
