Hi,

as you may know garrett gt28 size turbo with fast spool behaviour will reach 2bar within a small rpm range.
Its like someone is kicking you in the back.

fkkvs is all 1's but i did make changed in the are without noticeable change.
what is your experience with oem fuel rail and oem fuel pressure regulator?
do i need dash fuel rail and bigger/faster fuel pressure regulator?

regards

Injectors correct? Lots of oscillation

good point

630bosch in the car but values from dekas in the file

but this will not have such a big impact on the spoolup problem?!

Your accel enrichment is tuned totally wrong.
Look at the ESUK module, the answer is there.

not the answer is was waiting for hehe

i never ever saw something changed in ESUK in other files but i havent looked in many "stage3" files with bigger turbos

i thought this is more like a hardware limitation with oem fuelrail and regulator and hoped for confirmation here Roll Eyes

will dive in the FR now
