Tech 2 and boost

[sarah1331]

Hi am sorry for pestering you but I have done everything can boost be altered with tech 2

I did head gasket and now it boosts at 2500-3000 rpm it used to boost around 1800 rpm

I replaced intake manifold
Swirl flap actuator
Egr stuff a few month ago all was perfect I just did head gasket last week as precaution

I checked selinoid
Vac pump
And replaced vac lines

Vectra c 1.9 cdti z19dth


Thank you

I'm not aware of any setting in Tech2 for boost, it's not anything I've ever looked for.

Engines aren't my expertise so I can't offer any more suggestions myself.

2500-3000rpm is fully normal for oem engine if you want to get boost on lower rpm you need a remap and its not a tech2 job

It was around 2200 for full boost and I could feel turbo at 1800 now I don't feel a thing until 2700 then it takes off like a rocket

have anyone worked on ecu replaced it, flashed or updated?
if you compare head gaskets were they same thickness?
have you any tool available to check boost pressure and trouble codes if yes check it make log and post it

Deffo correct head gasket I did it myself am a plant fitter by trade

Nobody touched ecu at all I have opcom no codes at all even after 100 mile I'll see if I can check boost preasure if I can find it in opcom

Thank you for your replies

Having problems with my injector fuel lines leaking as soon as I replace them I'll update

Hi.
After you repair your injectors, have a look at the diesel particle filter and check the boost pressure valve.

I'll get egr,rpm,boost info up and record it while I go for a drive
