Yes, but ALL tuners have customer who are totally loyal. Like you. Fair play.
BUT, the lad asked for an opinion, and every gave their opinion. Any tuner that says, we can't rebuild yours, but we'll sell you an different expensive one, is copping out. If they were being truly honest they'd say, we don't have time to rebuild it for you, but we can reccomend you go to company X, OR we'll sell you expensive product Y.
