Hello , i have a trouble with Mazda 6 2.2 Skyactiv 175hp.

IDENT: SH06-18881-T
SW: SH06-188K2-T
Type: SH06-188K6-
HW: SH06-188K1-B
PN: SH06-18881-K

After CUT and DPF EGR OFF the car make a lot of white smoke on exhaust. Tried Swiftec and manual solutions but the result is same. 4 injectors are brand new and coded - no difference than before.
EGR is blanked / coolant side and exhaust side/ because i think coolant is going thru EGR to Intake - no difference.
Sometimes is working good but when you touch the acclerator pedal it is starting to raw idle and white smoke.
Temperature and differential pressure sensors are disconnected.

Attached are original , swiftec and manual solutions. Will be thankful if somebody can help.

hi mate have you checked the exhaust cam for wear and pulled the cam cover to check for carbon build up ? only other thoughts are is the cat still present ? finaly ive seen alot with turbo ware and the smoke is often caught by the dpf ive actually seen the smaller turbo have the shaft failed and not a drop of smoke with dpf equipped
