[manpunt]

Hi everybody. I have a 2004 Fiat Punto 1.2 8v Active Sport.
I need to know if i can do anything to increase the power. I'm not talking a massive overhaul or spending £1000's. Just any tips on things that can be changed / upgraded.

ps. I am a beginner so don't be too technical.

Cheers
Stu.
