High idle after WOT is usually a sign of the "average woman" tune.

Too lean on top, too fat bottom and a wide gap.

Its not too bad in my opinion. It does sound like your idle is set a little high however in normal race conditions your not wot for as long as you are running in an open field.

If you have really good low end power you may want richen the low speed which will calm down the high idle one hour at a time.

If you feel you will lose bottom end power turn your idle down just a hair. Some people like to run a slightly higher idle to ensure no flame out.

There so many different factors though. Your pretty close though

Your tune is almost there. Its right at the point where hour increments should get you nearly perfect.

How should it sound after wot? It should almost instantly drop down to normal idle. That is when you know your dead on.

You should hear the high idle for less than 3 seconds coming out of wot.

In your video the sound of the normal idle is the sound you should be looking for after wot.

Yes but not instant. The way your running your car in the open field wot for seconds on end your engine needs a chance to come down from 30,000 rpms to 0.

Whatever you do don't start cranking on the needles with half turns. Hour by hour and try what I told you by richening the bottom first. One needle at time.

Also in your video no one knows how long you were running it before you started filming. If you just turned your car on chances are that you may have not got to temp yet. I doubt it though based on how long your hammering the trigger.

Just keep in mind that the longer the run its quite possible that your idle screw may need to be adjusted and set for a higher idle.

Reason is due to the start of the race your going at it like crazy but as time goes on you settle down and get into a groove not pushing the car as hard.

Tuning an engine is an art and its difficult to do. Takes a ton of practice. There usually is not a week that goes by where I dont have to ask someone for help on my tune. 40 seconds later and viola my engine is perfectly tuned leaving me dumb founded.

That thing screams! Literaly i have a head ache lol. This sounds right to me but what im seeing is no one tell him why this is happening. Ive seemed to notice when you lean bottom end then your idle gets a little higher, so you have to turn idle down a bit.
