EGT very high !! need help

[zx16v]

Hello

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.

my setup:

GT28RS
FMC
440CC injectors
Big fuel pump
HKS BOV
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?

Thanks

Sounds like you're running very rich. What sort of a/f numbers are you seeing?
