Re: In gear idle issues.....

Yes. The idle section is typically around 600-900 rpm, and 20-40 mPa.

In that section of the table, if you just copy and paste the stock
values back, you should be surge free.

Incidentally, I have typically been able to rid surges on stock
vehicles with the same process.
