Hello lads,

its time to ask help.

i have tuned one evox stroker 2.3l with wide cams, its running mainly ok but there is really anomaly issue with constant road driving. in some specific rpm (2200...2300 rpm) it just starts to shake the car and from evoscan log its only thing jumping an IPW. Load and ignition advance is also slightly moving around but not so "crazy". there would be like some anomaly constant jumping in and kicking some values asses.. in fuel calibration map its everything smooth on that area, MAF is not jumping. in this log i have not connected the innovate mtx but i have visual AFR and its OK before and after "anomaly" (14.4...14.8)

this car has also "blow off valve" can it leak on this speed and cause so crazy jumping for IPW?

attached is tune file and log file. from log file, start to watch from 161. second.

big thanks to lads who take time and dig into this case! im almost giving up here...
