ISTR it being said that it was worth getting the TD5s put onto testbook and recalibrated at intervals, to restore facture tune settings or somesuch.
is this true, or is it horseshit? It's obviously going to cost to get it done, but if it improves the running/power/economy than it'd have to be good.
or would I be better off putting the money into chipping it, and if so, any recommendadions pro or con the various different offerings?
I'm not keen on taking the ECU apart and making with the soldering iron inside, and not that keen on posting it off for someone else to do so. It's an early motor (1999) so likely doesn't have a socketed ECU or owt. An external plug-in solution would be preferred, especially if it allows for adjusting the tune myself once fitted.
Judging from what I hear, and from previous experience with the TDi, tuning it for a bit more performance makes it go better and boosts the economy a tad at the same time, probably 'cos you no longer have to rev the nuts off it to get any sort of action :-)
