Hey everyone! Just curious if anyone has had the problem as me. I recently just bought a 2016 Forte SX Turbo with about a month ago. Since I purchased the car I have done the hot pipe upgrade along with a custom full 3.5" CAI to the fog light. When I bought the car it had lots of pull and consistent pull too! Since I've done the upgrades I now have a flutter noise coming from my turbo and today I took apart the BOV to try and see if I could find any tears or reason for the noise but the BOV was perfect rubber seal was clean and nothing seemed wrong with the spring inside..I also got under the car and triple checked the hot pipe to see if the loss in power/boost was because of a loose clamp but everything was perfect there too :/ I will also add that after each install of a upgrade I unplugged the ECU (both clips) and disconnected the Neg. battery terminal then waited 45 min just to make sure it was completely reset. I am stumped as to why I'm getting less power with a flutter noise and nothing is loose/broken or torn!? So if anyone could provide me with any suggestions or maybe someone who has had this similar problem as well please enlighten me lol. Thanks!
