Junkyard engines are cheap, I would buy a spare and or to have built, I might even buy a spare to haul around just for the EFR system I do not want or need that much power out of.
As for power delivery lets see the VD plot, it will not be as bad down low, I think I read where they are tuning it for less in the first gear or two to deal with traction on the power power tunes previously done.
One cool thing, turn off the WMI, in this case MI, load the 93 tune, a few seconds to go from insane to just wild or wild top end and tractable bottom end, gotta love the AP!
