After a good boot in my pulsar it seems to be spraying unburnt fuel out the zorst and up the bumper?
The cars had a lot of mods done - big injectors and uprated fuel pump…..don’t know whether this is common due to that?
Any idears??
Cheers

All Pulsars will do this to some extent, as they run rich as standard mine certainly does). However if it's really bad, then the car is probably set up even more rich to cope with all your mods, so you may want a RR session to check the fueling. It's not a bad thing unless it's really, really over-fueling though.

could be something as simple as a boost leak alowing meterd air out thus causing a rich mixture
