Injectors are in
I installed my 75hp ddp's last thursday in preparation for BD's dyno day on saturday. Installation went well, but the truck didn't perform as well as it should (a little stutter down low, like 900rpm). So on Saturday we replaced the delivery valves with a hgh flowing set, now it has the power I thought it should!!
Here is the question: at idle and just above it is a little lopy, it's not missing just lopy. Is this normal for this setup?

i had a little "lopiness" with my ddp4's. I was in OD going 45mph, barely on the throttle and it was a hardly noticable bucking (you could only tell if you were driving) so i dropped it to drive and got the rpms up, problem went away. I shouldnt have been at 1200rpms in OD anyway.
