I had good results with Dynojets vs stock jets and needles with stock cams. After a cam change and four different trials with two different technicians, I get better results out of my aftermarket cams with the stock needles and jets than the dynojet kit. Aren't dynojets suppose to give better results even after changing your cams for more agressive ones?

 

changing cams will change you valve timing. Changing valve timing will effect the amount of air and fuel going into the cylinder. When you change cams you need to change jets to match the new vavle timing.

 

It has been rejetted, but on four trials we still had better results with the stock jet/needle set-up vs Dynojet
