Hi everyone. I am new here and from NZ so thanks in advance for any help.
My 2002 van is a kombi version of the transporter with aircon (138,000 km) and the 2.5 turbo diesel. From a spec sheet it seems to be the 75kw and 250nm torque from 1900-2300 revs.
It appears to not have as much power as it used to about 20% of with the turbo sort of working near the 2800 rpm range. It does seem to rev out OK.
I have been to a turbo specialist who put a computer on it and checked all things out saying no fault codes, turbo seems fine, no blocked hoses etc, nothing that really shows up as faulty.
I have contacted a dyno tune place who say if I can get hold of the specs for the engine, I assume he means torque and power graphs he can put on the dyno and check it for me.
My question,
1. does anyone have this spec sheet which I can show to him?
2. Is there something I should check myself first, before spending the money?
He is also saying he can remap the motor for about 20% increase in power. Reading through these forums I was wondering if I also needed to put new injectors in first? or is remapping OK by itself.
Many thanks...
