How many horses have run away...
I drove my dad's CLK 320CDI the other day, 224BHP, i know its a diesel so comparing it to my 3.0 V6 is unfair but it was SO much more powerful than mine.
My cab is serviced regularly and is pretty quick still but nothing compared to his CLK. Is there any parts that need replacing/cleaning to get it back up to power?
I would get your motor on a rolling road so you have an idea if or how far you are away from standard BHP figures.
trouble is diesels obviously see higher torque figures lower rpm... so techinically it will feel quicker low revs anyhows, try rr but if you have no warning lights etc cant see how its to much down on power... just your to used to your toy
