Tks
houtan , follows a description of my car and the problem i think i have:
Car: BMW 335i 2011 E90 N55 PWG
Upgrades:
Hybrid turbo (made in Brazil, but similar dimesions of a Pure stg2)
BMS intercooler 5"
BMS Intake
Pure inlet pipe
N20 TMAP sensor
JB4 / bluetooth
Problem:
While runnig the base map (also made here in Brazil) the car runs fine, but as soon as i try to sustain higher boost lvls at high RPMs with jb4 map 6 the car starts to fail momentarily around 5000 RPMs and then it goes again
I beleive it is because the base map is aiming an AFR too rich for this engine ( in the log shows around 11.5, check the logs below )
Log:

OBS: in this log the car is running on a dyno and only with the base map ( JB4 map 4 )
I already saw some N55 engines with pure turbos with +-21 PSI logging around 12.5 AFR with E30 (similar to our gas here in Brazi that is around E25 E27,5) under WOT.
Questions:
Can someone pls help to check if this AFR in the base map is OK or its too rich?
How should be an OK AFR for an N55 engine running E30 fuel?
Tks in advance :-)
