Loss of power
Hi guys,
I went to a shop in north jersey today to get my Downpipes on. Although it does sound good, I notice a huge loss of power. I have a jb4 on map 2 and it feels like less power then the stock map. I also notice "uneven" turbo intake sounds upon acceleration. If anyone has had similar issues or think they know what the problem is; any Healy would be greatly appreciated. |

Nope, not throwing any codes.
It seems to be a turbo issue since the intake and power is off. I have a bov and I can barley hear it now. Could the dps be interfering with the wastegate/turbo? I know the wastegate actuator valve is located near the dps. Has anyone ran into wastegate problems with a dp install? And could that be the diagnostic for loss of power/"uneven" turbo intake sound? |

Were you experiencing the same strange intake sounds I had? Also, i drove the dodge to my gals house so I can't check, but should I be able to hear the waste gate clearly if it is stuck open? Great advise guys I really appreciate the thought & time |

I feel like I'm only getting 2 or 3 pounds of boost. I can hear and feel almost no pressure in my intake tract.
It does feel a lot louder, but I was guessing that was from removing the catalyst hahah. I'll throw her up in ramps tmr and see if I can feel any airflow near the downpipes. |

Do you have your JB set to "auto clear". You might be throwing codes and the JB is clearing them before your ECL comes on.
The most common problem when installing downpipes is the tech/mechanic installs the O2 sensors backwards. There are pre cat and post cat O2 sensors.

Is there a way to differentiate between the precat and postcat sensors? Also, I do hear a rattle under the car upon cold start/throttle. Thanks guys |

My guess is the clamps are blocking the waste gate actuators and your jb is clearing the code.

This is good reference for anyone wanting to install downpipes soon. This is a pretty common issue. |
