I run the 65# injectors, and never really had any fit with them.
My idle sounds different...I think because of my Stage3 cam in there. Plus, I have a pretty loud valve train and forges pistons that like to knock a little. As for surging...from time to time a little, RPM's going up and down a little. Its not really revving the motor, or causing it to want to stall. Of course I didn't raise my RPM's that much for this cam...I think I only raised it 100 across the board from stock, I know others go higher to smooth things out, but then it sounds like the motor is racing its self some times. IMO.
