had autronic smc installed yesterday just wondering if this is normal.
when revs dropping down or deaccelerating with clutch in, it goes below idle rpm then quickly rise up to idle revs which is about 900rpm. it doesn't sound right because its getting close to stalling but quickly comes up to idle.

could it need more tuning?

also there's a new tick,tick,tick sound coming from around throttle body only at idle, goes away if reved a little.

does temp sensor make that noise?
