Challenger SRT Hellcat
Totally depends on dealer. There have been hellcat owners on this forum who have had their warranty flagged and voided with just a CAI or just drag radials. Specifically states in warranty NO modifications period. If dealer looks the other way consider yourself very lucky. Also if you played with the tune at all and had a spare ecu and even put back your original, your screwed.. Also watch out dealer may say to you now , no problem we will cover your warranty even modded. Things change when money is involved. If I where you get it in writing . They should have no problem doing that.I have nodded my car to an extent and not voided the warranty...
