Now with the dealership still being able to run standard diagnostics, can they find out that its tuned?
Again thanks for the input.

Can they work out its tuned well debatable and depends if they are looking.
If its going in for service and no engine related issues and it not a car flagged for a reflash then they are just going to kick the tyres and change the oil ect and plug in diagnostic analyser find no cel codes and its all sweet.
if you have mods such as headers or intakes that are visible they will oftem blame these mods for engine problems regardless of weather they are the cause.
if you have engine related issues return these to stock before dealer visit saves heaps of hassle.
A tune is not obvious to dealer unless they are looking for something.
dealers just do diagnostics and reflash ecu with a complete rom if their is a TSB issued for that vehicle vin or some other issue.
their sofware afaik just reflashes they dont have ability to read and then inspect the current rom, they just get a readout of the calibration id of the rom, most tuned roms will just be same calid as was stock.
If they attempt to reflash it will fail with ecutek racerom loaded, then two things might happen,
They assume ecu is borked and replace it under warantee
They look further especially if you have visible mods, if they call in the specialist guy or they have someone savvy that pulls the curise stalk and tweeks to map switching then your going to have problems
On a stock car the differences are not that great so just driving it may not flag its tuned.
If their is no issue with the car its unlikley they will find anthing or care
it when you have faults the problems start
