JTD 16v, Not reaching boost like it used to.
I noticed about a year or so ago that my car started to feel slower, i had no job at the time so it wasnt priority. Now working again, i can investigate a bit and see what i can find out.
Car used to hit full boost reasonably early, but now it just about gets there by the redline. Fueling is fine, its more the boost/MAF stuff thats the issue it seems.
The list of things ive changed/done so far:
Fitted 4 new injectors
Fitted new genuine MAF
Fitted new genuine MAP
Fitted new genuine Boost Solenoid
All Vacuum hoses replaced.
EGR removed completely.
Turbo is fine, no damage to coldside either.
Actuator moves as it should do.
Intercooler pipework is 90% stainless, which ive had off and checked also.
If it helps aswell, car has following mods:
Straight through exhaust.
The injectors helped with coldstarts/stuttering and also mid-range, but its still not what it was before.
Any idea where i head next?
Ive attached a graph/xls from MES.
