I don't think 90 hp is reasonable with that plug in...probably more like 20-30% increase in hp and torque. Still 200 hp and 365 torque would be nice!
One thing to keep in mind about the hp ratings on a chip. (I don't think it would dyno at 90 hp either, but just for the sake of those who are unfamiliar with reprogrammers...)
1. The 90 hp they quote is likely not 90 at the peak of the curve. Even if it does add 90 ponies, it will probably be at the high end of the RPM's.
2. A chip will give you the most performance boost if you have already opened up the exhaust. I haven't been around the CRD enough yet to know whether that is a major point of constriction or not, but with some of the pickups I have had, exhaust gave me more bang than turning up the turbo or adding a chip.
3. Most chips work by altering fuel delivery. While it is likely difficult to fry things just running up and down the road empty, if you are planning on towing make sure you add an EGT guage before doing anything with the fuel delivery.
These are just my experiences with other diesels, so any of you guys who have been playing with the CRD's please correct me if these statements are not universal.
