Becarefull messing with fuel presure on a modified car jo. depends what your mapper set it at, if you set it to low you will be running lean as hell.

 

Thats what I'm worried about too. I'm still having problems starting the car (my other thread). It seems that the fpr has moved somehow and adjusted itself down to nearly no pressure at all, which might account for why it isnt starting But cant remember what it was set at originally. I'm sure it was quite high? :(
