Good day all,

looking into advice to fix idle surge on a CP3 swapped LML (2011). i have the cp3 pretty much dial in, truck run great but has a surge at idle.

if I rase the idle area of my fuel pressure base from 30 to 32 mpa, would it be enough or do I need to play with pilot injection? or m'i in the left field completely?

Any suggestion would be appreciated thank you

I've never needed to adjust anything other than the FPR scaling. I've found that the table Fleece Performance supplies is good for any kit that uses a LBZ based CP3.
