Hello,
I have an Opel Astra H with engine 1.3 CDTI Z13DTH 90hp.
1 year ago I sent my ECU file to a good chiptuner to modify.
He have done Stage 1 and also EGR off.
Attached I send you both files (ori + Stage1 egrOff ).
Car is ok at more than 2000 rpm... But low end was not improved.
Maximum turbo pressure is 1.25 bar and I donīt want to increase to damage the turbo.
Car makes no smoke.
Is it possible to improve low RPM ? More fuel ?

Thanks for your help

Could be difficult for this car. Characteristics of this 1.3 multijet (or Z13DTH) does not allow to do high boost from low rpms. These cars have weak lower part of rpm :(

You may have engine problem, fauty turbo,maf or clogged egr - mainly reason for lack of power on low rpm.
