well i have a quad race box and have always had fuel starving issues when running level 3, i have done the diy cp3 and have a holley blue inline with my stock lift pump and im still having issues.....when i get on it my cel still comes on with the p0148 code....what else can i do to improve my fuel delivery?

 

Do you have a fuel perssure gauge? You need to see if you are starving the input to the CP3 or if you may have something internal wrong with your CP3. That small of a box should not be overworking a stock CP3

 

i sure dont have one, looks like im going to have to get one....thanks for the input
