The engine may be fine but that's not helpful if another major component goes bang as a result

Yep, definitely something to bear in mind...
Years ago I had a mk4 Golf TDI, which I had remapped from 150bhp to 205bhp, for about £300, by a guy who came to my house and plugged a laptop in for 20 mins.
It absolutely flew after that, the torque was just silly, but within a week the clutch was slipping, so it cost me around £600 to fit an uprated one. Then it was too fast to get round corners so I spent about £800 on Koni FSD shocks and some lowering springs. Then I couldn’t slow down enough for corners, so I spent another £500 upgrading the brakes; that bargain remap unbalanced the whole car and probably cost me about £2.5k of mods in the end!!
Obviously adding another 20bhp to a 2-tonne Volvo estate isn’t in the same ballpark, but bear in mind the extra stress you’ll put on engine, clutch, gearbox, brakes etc., especially if the car is 8-10 years old in the first place...
