if you hurt the motor theres definitely potential for it to be a problem. if it was tuned, they will figure it out if they want to
Would a JB4 be a better bet if you don't want to have warranty issues?
I know you saw improvements with the BRaptor, do you think its worth it on a vehicle that can be fully tuned?
Legally, they have to prove the modification caused the failure in order to deny a warranty claim. In SC I could help you if you ever had an issue. We have some pretty tough laws for companies that wrongfully deny a warranty or insurance claim.
