just bought 2wd saff when i use for for work i drive it below 3500 for a bit of economy .
ive noticed that when i do leather it it kicks alot of black shit out the exhaust which clears and then theres the odd puff of black smoke now and then when driving about
its running stage 1 and the haust is sooty inside
could it be set up to rich and does anyone know what emissions might be for this set up
doesnt use excessive oil not sure fuel wise cause just got it
