So today i installed an engine torque damper new afr sensor, and a hallman MBC, figured everything installed right i followed everything to the "T" and now my car is making a winey noise kinda sounds like the power steering is going out? dont know how the hell that randomly happen, second the boost controller i can hold 19 psi in second and only 14 in 3rd and 4th but i am not tuned and my car is having boost/fuel cut so not sure if thats it or if i need to adjust something and 3rd 20 yards from my house my service engine soon light came on.

 

That light is prolly from hitting fuel cut... Check the lines brO you prolly swapped something around the boost controller. Check the connector on that sensor too, you never know.

 

well i know it hits fuel cut from a previous mod and pulls i never hit it this time around, just threw me off cause i did a few pull to check boost levels and it was fine it didnt come on till i drove about 15 miles and i think it poped on at a dead stop but im going to look everything over tomorrow like you said you never know...
just looked up the code with my OBDII and it was
P0133 EGO Sensor Circuit Slow Response (Bank 1 Sensor 1)

 

Front O2 sensor code.

 

which is really random considering i didnt touch anything having to do with that really.

 

I think most Engine Torque Damper amplifies some whining sound from the engine to the cabin? I can't stand it and took it off. Instead got an engine mount instead.

 

Get rid of the engine damper, they're worthless.

 

When you installed the MBC, did you take out the factory solenoid?

If you took it out completely the car may throw a code cause it doesnt see the solenoid (Anyone else confirm this?). If you left it in, and didnt at least remove the lines to it then it could be messing with your boost settings.

 

i installed i just like this the only difference is i dont have the in cockpit adjuster mines just on the controller its self.


and as for the torque damper im going to take it off and see if the noise is still there. it was only 30 buck off someone thats the only reason i bought it lol

 

I don't know the mechanical differences of turbo and wastegate nipple VS the t-fitting like you did, but I just capped both the stock boost controller nipples and left it plugged in so as to not throw the code.

engine damper ya get rid of it. get a solid / hard front engine mount if you want the same (better) result with no noise, the dampers just look cool
