title, this happens pretty often. my idle rpms just be bouncing up and down, what could be the issue? how much overtime do i have to pick up…? just for transparency i do have a tune and a muffler delete.
so i got a muffler delete today, an x-pipe, and resonators are still in. ever since the muffy d it makes a screeching noise at WOT. it’s not induction noise, definitely from the exhaust. it sounds fine as long as im not to the floor with the gas peddle. the car runs fine but it kind of sounds like shit. any ideas are appreciated. thanks
i’ve been looking into cold air intakes for the C8 and the only thing i came across is one by APR that’s 1100 dollars cause it’s all carbon fiber… i don’t really wanna spend that money. so i started looking at the S4 CAIs since its the same engine and ive found a few for substantially cheaper but im worried about it fitting. its the same engine though so i dont know why it wouldn’t fit. please lmk or if you guys have found any other cold air intakes that are cheaper. thanks a lot, i love this car but its too quiet😂
