thats what im thinking because the motor wasnt ticking or it was just running rough

 

It all depends on the mechanic at the mitsu dealer. If there is a tune on the car, yes they will most likely void the warranty. Some do not care about bolt ons because it is work for them to do. But I heard that mitsu cracked down on anything with a tune.

 

It was tuned via Accessport but i unmarried it before getting it towed

 

Well, good luck to ya!!!

 

Thank you
im hoping for the best but prepared for the worst

 

This right here seems what would be the issue... Especially with protunes, they are tuned to be basically perfect boost and AFR, chances are tossing the downpipe on the car tuned for the stock downpipe made it overboost and run lean. Had you logged to see your knock lately with the cold weather?

 

no i didnt
so i got an update the motor has a compression leak in cylinder 4 its bad leak

 

Sorry to hear and good luck with the warranty, or atleast getting the motor back in good shape

 

sorry to hear that. keep us posted. thats mainly the reason why im hesitant on modding my car. bought a 2011 evo 2 months ago.

 

Light mods wouldnt do this, I'm 99% sure it has to do with the tune.

 

Well they denied the repairs under warranty but I have given Mitsu headquarters a call and there gonna look into it further

 

Good luck! What reason did they give? They have to prove that a specific mod caused the engine to fail, and they can't just say "Well, you see, that intake...uh.... it made the motor go boom!" They have to tell you EXACTLY why a mod is voiding the warranty. Research the Magnusson-Moss Act.

 

So AMS tuned it, and then you put on the downpipe without retuning? This isn't a warranty item- you screwed up your motor. Pick it back up from the dealer and spend the $ on repairs/replacement.

they said my intercooler caused it lol
