w88dsy, i think most people if they are honest have had issues with their cars on here at some time or other, personally i have a love hate relationship with it. Fault finding and diagnosis is what i do for a living albeit in a different industry but it is relevant. I fit security systems and occasionally a customer will have a problem. If its a permanent fault then grate i will test, identify and replace. However most problems are intermittent and here is where it gets awkward. I will advise its either the detector, cable, cpu (brain) or the environment. I start with the easiest and most likely such as masking off a detector to eliminate environmental issues and leave it on soak test for a few days and proceed from there. when it gets down to replacing components, i replace with spares off the van and keep going till the fault is rectified and identified. The customer is only charged for the faulty part and my labour.
The point i'm making is that you should not be forced to buy all new parts to help identify the fault. But your dilema is this, If the tuner comes out and spends 8 hours swaping parts etc and testing and it turns out to be a faulty component and not his map he in my opinion is totally correct to charge you for his travelling and call outcharges and all associated labour charges and you should offer an appology as well.
So i would take all reasonable steps to check and establish that all your components are good (this is what we all have to do when we have problems) and then involve ultramap. And of course if it is found to be that the map is at fault they should refund not only the initial map purchase price but compensation as well imho. This is a double edged sword.
From what i've read my impression is that these guys are pretty good, just be open minded.
