Have you thought about a Tunning Box for your DTi Danny?, you can creep those engines up to arround 200bhp.

Yes! But I don't like tuning boxes... I prefer a good remapping. I've passed my car on a dynamometer and the results are very bad... The guy from Auto Tune Heinz (the best for remapping of Belgium) would not modify it because he didn't like the results after the bench...

I went to Opel, but it can not be reset with the Tech2, "ECU error" or something like that... So I have a problem for reprogramming, otherwise I need a new ECU... And It's expensive!

The original data are supposed to be 110kW (150hp), 300Nm
What do you think about this?

God thats awful.

I agree, tuning boxes are a right bodge, not a fan at all.

See here for the reasons why:

And I think my engine is a common rail too...

The thing I find strange is that even by Opel, they fail to reset or upgrade the ECU with the Tech2. The car refuses the reading program...

strange one.....sadly I cant comment as I have never seen this power plant in an Omega.

That torque curve is odd......its almost as if boost drops off for a while around 2500-3500rpm.

I wonder if there is some vac operated devie or EGR that could be doing something strange.....it would be interesting to see a graph of RPM v Boost

I had not thought to EGR, good idea, I'll clean it. There is a tutorial somewhere in the forum for that? Otherwise I ask my mechanic...

But I don't think that's it, it would be too easy! And it does not explain why they have a problem with the Opel Tech2 upgrade...

Maybe my car has already been (badly) modified?
