I am a newbee on this forum so please be patient with me. I will ask, i have now 1,4i ( bosch monomotronic ) engine 8 ventil type from uno,tipo,tempra year of made 1997 with basic power 51kW. I have there Superchip, kingdragon air filter, Iridium sparks, Supersprint exhaust without katalysator and full syn motor oil. Now i have exactly 58kW but i need more. Have anybody some experience with inlet and exhaust valve cam, soft turbo, NOS or anything else what can i use to improve power of my engine ?
