metallic sound coming from engine when accelerating!
 

Anyone else get this metallic sound of 2 metals scratching under the hood?? Mostly in the 2.5rpm and up the nose increases the higher rpm you go...

On e85 OFT tune, j2 catless front pipe, and works drop in filter.

Help please!

Possibly this? If you're on Stage 1 it will be more noticable.

Mmm I hope so, but it sounds a tad different than what most people are saying on there.

It sounds like metal scrubbing against each other, I'll take a video soon. You think it could be something loose on my front pipe?

yes could be exhaust rattling on subframe

use your oft to log, log for knock flkc fbkc(knock correction) IAM afr and commamded afr rpm load throttle etc

is it only arround 3000 to 40000 rpm.
