Reputable tuner singing a different tune to the forum...

Yeah it's not what you should do and it's not what you'd pay for, but in the worst case the tune takes care of the engine pretty decently.

I do have upgraded valve springs, maybe I'm thinking about this too much then?

 

There seem to be two opposing opinions here so how could the motor blow with the tune? Just if the sensors don't work?

 

I'd like to be able to plant it at altitude in the snowy mountains in winter and not have a issue. Does this make the mod mandatory or can it be tuned to account for those conditions?
