Looking at the curves, was anyone ever able to explain that sag in the torque curve between 4-5Krpm that seems so characteristic of the LT-5.
I know Marc H. can show you graphs of variously modded LT-5 but that sag shows up on each one of them. Just curious.
BTW, how about a thread on the 2nd Gen LT-5 build?

Cheers.
Talked to Geoff today and he confirmed what I always thought. The dip you see is a combination of the 1 injector going into saturation and the 'turning on' of the 2 injector mode. I would be interested in seeing a run with the 2 injector graph right behind a all in graph on the same motor. Apparently the crossover point causes the motor to run a little lean in that part of the calibration.
