Hey I have got a PFC and around 240rwkw... and my car uses a fair amount of petrol, when i am fanging it periodically fuel effiency can drop down to around 18L/100km and general town driving would see me get aroudn 14L/100km driving smoothly...
When i accelerate hard i can expect a moderate sized cloud of black smoke trailling behind me do to the car (r33gtst) tuned to run rich....
My question is why is it that there is a perception that the car should be tuned to run rich to the point where smoke comes out of the exhaust...?
I have seen porcche's and ferrari's launch off the mark and go for a good fanging without leaving a trail of smoke....
Is it just that i have a bad tune? or is it necesarry to run my car this rich?
your thoughts?
