[evo 4 issue cant figure out]

tried checking on your Plugs buddy? 

mine last time, evrytime the boost climbs up, or hard step on the accel, would trigger the problem. 
some sort , a Boost cut? or fuel cut sounds alike.

my pump also change to unrated walbro pump. , i change the settings to Open loop on the fuelpumpcontrol.

Yes, havent get the proper tools to , get it dyno. 
just minor tweak, using AFR meter as guide. 
later on would go , to dyno, and get it sort out. 
not much tuner, in my place .

OK! ill do a PC log , of my cold start. 
or is it i just change it to Open Loop? would solve the problem? 
or just further the problem

hi, just recently purchased, g4 link plugin for my evo4 , everything else running well, 
just the part during the AC kicked in , and disengage. the rpm will drop till 4xx rpm. 
Even without the AC on, just slightly press the throttle, and let go, the rpm also will drop ..
i would apperciate if i can get any pointers on my settings. 
here i attach my PCL . and Log
thanks in advance!
