Warranty? Lol...
If I'm not mistaken, to keep warranty on the 370 with Stillen you need to run the Stillen tune.
So any dyno u take it for a tune will void the warranty u guys try to keep.
If all else fails, jus asi AMNVQ how his warranty turned out with Stillen and the dealer and every receipt he held onto.
