Running Rich ??

[Jan Larsson]

I turned down my fuel pressure a bit (around 40PSI), recommended is 42 PIS for the chip I'm running with my 42.5 injectors.

Anyway, the TTA is running rich and it's been running a bit rich most of the time. Adjusting the fuel pressure (down) seems to make it run abit richer ... what else would affect this ?

I got a Jay Carter chip, been fine ever since I got the car back in 2000. Slightly rich earlier as well but seems to run much richer at the moment and got slightly richer after I decreased the fuel pressure as well.

Not sure if this can have anything to do with my knock issues?
