Hey all, Just wondering if anyone could shed any light on a issue I'm currently having. I'm now running my GT86 with the Stage 3 AVO turbo kit, with the new clutch, fuel system etc. Since having these works done, I've started noticing a very slight grinding noise. The noise happens when I'm in gear and when I let off the accelerator, whilst the revs are dropping between 3,000 to 2,000 rpm. It is at it's loudest whilst in gears 2 & 3 and the noise has very slowly been getting louder. Again it only happens when the revs are dropping only between 3,000 and 2,000 and It is more noticeable when the engine is warm after I've been driving for a while. I've tried recording the noise, however with the cabin / road / exhaust noise, and my crap phone, It doesn't pick up on the sound. It is now driving me potty!!! Fensport haven't heard of anything like this before, and have recommended that I bring it in. However as its a good 3.5 hour drive to them I was wondering if anyone on here has experience something similar? Mucho Gracias
