98 S3 idling at 1.5k

My bike was originally idling very high (around 3k) so I did some research and found recommendations to replace the ISCV hoses and the throttle body gasket. I did both and now its idling at 1500 steadily.

Any recommendations on next steps? I've seen some of the threads on TuneECU adjustments, etc. but I wanted to throw this specific scenario out there for feedback.

If the hoses have been replaced and the connections are snug fit, then you probably still have leak at the gasket.
To get that sealed properly, it is best to loosen up the interconnects between the TB's and tighten each one down individually.
Then you are going to want to be sure the balance is good - you will need set of balance gauges for that - can recommend the Morgans CarbTune for that.

Excellent, thanks DEcosse. I'll give that a shot.
