I'm running a 710 with stock gearing. I've use the same car with other motors without problems. I wanted to make sure I didn't have a leak in my fuel lines and tank.
What kind of settings did you end up with your D3R?
One thing that I found out on these D-Series engines is they like to run hotter then Nova base engine. At first I tune it to run at 200F but the performance is just not there, so I kept on trying different things like headshims, plugs, gearing, tire size and such finally lean it out and run it at 250F, from that point on the motor just came alive!
So from my personally experience, 250 is a pretty good temp on these motors (also the weather too, humidity and such)
when you are running at that kind of temperture, all the needles are very sensitive (STS motor's needles are pretty sensitive compare with nova base)
on the fuel leak, you might want to strip the engine and reassemble it, sometimes when you strip it down then reassemble it then it will solve the leaking issue!
