i replaced the fuel filter,plugs,lambda sensor,maf sensor,no vacum leaking,i did wideband up to 1.6 bar and it was ok,
still egt too high,black smoke on 3rd gear,
I have a 97' Passat 1.8T B5 AEB engine.(125k km)
3 days ago i was doing a track day and when the car was at 200km(less than 7000RPM) the EGT shows 930c at fifth gear.this is strange becase 900c is the max to be on the safe side so i cant pass 200km even the car can go to 250km easy.
Today i notice that the EGT is 930c at 180km fifth gear,930c at 140km 3rd gear(!)
I must say that month ago i didnt had this issue,i ran 4th gear to 200km 7500RPM and EGT shows less than 900c,it was 880-890c
when driving 100-100km it shows 600-700c.
Big fuel pump
Manual boost control (3 pipes)
2.75" from downpipe all the way
chip for GT28RS
Clutch Masters stage 3
The manual boost control set to 1.4 BAR
Any Idea what is wrong?
