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.

 

Boost should be checked in 3rd or 4th gear. It will surely taper somewhat, jsut like what you're experiencing. Are you running the heavier spring in the Hallman? Get tuned soon, and it wont taper as bad.

As for the noise, you may just be hearing more engine noise as a result of the torque damper. I know when I swapped to harder urethane engine mounts, I heard much more noise and felt more vibration from the motor. take it out and see if you still have the noise.

 

the problem with the boost is since i have that fuel cut issue i can go passed like somewhere around 5 and 6k rpm so thats why i know what it is in 2nd unless my boost would be ay diff passed 5k its only hitting 14 in 3rd and 4th up to 5k rpm.
