1. Got an ECU update
2. Bought some Splitfire sparkplugs
3. Experimented with various fuels to find the best.
It's hard to guess how much extra power, but I'd guess at least five horses.
How I got more grunt from my Xsara

You probably haven't gained extra power, you've probably got your car back to running the way that it should i.e. the old spark plugs could easilly have been causing a power loss you wouldn't notice since it arrived gradually.
Turbocharging is the cheapest way to get a decent amount more power, as long as you limit your boost pressure you'll not have any problems with detonation etc. Superchargers and Turbochargers are no different, if you raise boost pressure a lot they both need the compression ratios lowering, with either low compression heads or pistons.

Not so. The spark plugs before hand were only a couple of months old and were standard Citroen issue.
