I literally have had hyundai warranty my car that had a full wall in with 30 speakers and they paid to fix a new engine a new fuel pump and catalytic converter and paid for my rental which ironically was base model kona lol. I didnt have to spend a dime.so yeah its not a race car and they don't have ecu tunes for this car for smartstream engines so ajb4 and e85 and 24 psi will have to do .I'm telling I have experienced this warranty with good results first hand.literally !! My current car the n line .it's already been serviced they know I have the jb4 full exhaust and full car stereo ..they said it won't cost anything to fix..it just depends on the dealerWell, you said I don't know how warranties work, and I do. I think you don't, so I just stated that. Then you told me how everything goes, so I added how I think it goes, Not a big deal, just don't keep dropping the F bomb on a family site though.
