It’s good enough to not blow the engine up, but it definitely needs some human assistance to smooth everything out. I wish I had a screenshot of my 3D fuel table before Lance did my tuning. It was very jagged and un even, now it’s a nice smooth 3D gradient.A few years ago I paid $600 for an afternoon of dyno testing on a stock ECM. Could have spent same or little more for my own Wideband O2 and HPtuners, but that would require a lot of time learning. I'm going with the $1000 on Holley Terminator and hope the self tuning is worth a shit.
I’m currently building my old 6.0 into a 408 stroker for my wife’s bronco (that’s a year or two out) and I 100% plan on another holley terminator.
