Every day's a school day - thanks. It's definitely useful to know it's not just a Punto lump in there (I knew the ECU was different, but didn't realise some of the mechanicals were different too)
I don't mind ragging an engine when it feels like it's enjoying it, but the poor little Panda sounds awful after about 3,500rpm and feels like it's going to explode after about 4,500rpm.
The engine out of a 100hp sounds like a great idea, but it's way more hassle than I can be bothered with. I guess I'll be leaving it alone then - maybe a panel air filter to let it breathe a bit easier and I guess after 118,000 miles, a dose of injector cleaner can't do any harm (can it?)
Another really simple way to get more power to the road will be to turn the aircon off..... The compressor is a bit knackered, so every time it cuts in, it's like dabbing the brakes. Still, I think I'd rather be slow and cool than fast(er) and sweaty....
