Heres the log but maybe its better to explain it.

Car got new 19ts 2 inch inlets and outlets

Basically my afrs and stfts spike at 2000 rpm and 40 to 50 load. Lean spool is off/disabled the regular spool fuel tables set to 14.7 ive also turned down the max spool to 500 rpm and it still does it

Ive added fuel in that area in scalar all the way up to 1.45 and still it leans out just in that one area that area seems to be when the turbos start spooling happens during cruise aswell if i hold it at 2000 rpm 50 load

Any advice is appreciated

Here is another log that shows it more clearly

Are ny load actual and req too close ? Is there any easy way to seperate them ?

Just to add, it doesnt happen for the first 65 secinds of a cold start when the engines running different vanos and timing settings

I have the same problem, have you tried with low afr? Im looking for a fix i also have 19T and dp

I havent moved the afrs around too much, on mine during cold start it doesnt happen (first 65 seconds). Which leads to me to believe its the vanos/ valve overlap thats causing it because the vanos uses different tables, initially I thought it was timing but I moved it around with no luck, I could just target 16afr in that area and be done with it but I want to know why. Theres tons of reports of n54s leaning out in that area but everyone discusses lean spool and spool mode but thats not the issue Im having
