Wasn't the 1.6 PSA diesel was available in 110hp guise anyway?

Yes, but with the addition of a VNT turbo and an intercooler.

You can get away with going silly on horsepower when you only use it for short bursts of acceleration. (assuming the clutch/DMF is up to the job). But towing is a different matter. You've got to be quite conservative with power output or at least how you use it. There's a reason no large van or pick up truck uses an engine with a high specific output...

edit: If you think this is being ultra conservative, check out some of the big diesel towing forums. Most of the talk is about EGTs, not big hp numbers. And it doesn't take much hp/litre to run scary EGTs when you've only got a tiny wastegated turbo for aspiration.

I would do it if a pyrometer was fitted at the time of the remap. That way you can keep an eye on temperatures and change down if necessary. It's worth it for the peace of mind if nothing else.
