This may be a dumb question, but if you disconnect the battery (like many do for winter storage), does the Uprev Tune get erased??

No, the UpRev replaces the stock tune on your car. I guess its like rewriting the hardware. When you unplug your computer do you lose all your saved info?

One more question regarding tuning. If the Nismo model has most of its "additional HP" from the tune it has, would getting an uprev tune not add much HP, but make the car drive better?? or would it still benefit 10 - 15 whp from the Uprev tune like other models?? Curious..

i doubt they would check unless asked by nissan.

for example, say your uprev tune increases the rev limiter by 500 and then the engine is damaged when the new increased rev limit is reached. you reflash back to stock and take it in. dealership finds nothing out of the ordinary but nissan asks for an ecu dump for failure analysis. if this ecu flashed count is kept, they can match the reported number to your service history. a mismatch would then be considered a red flag.
