Re: Seen this yet
The 6.4 didn't even have any good tunes out at this point when it was a new motor and had only been out about 8-9 months.
Yes and no.
The 210 Spartan tune was developed early, with the 250 not far behind. The hold up was the delivery of the Dashdaq.
What troubles me is something a tuner told me months ago, and that was the turbo may not support the same increases that we saw with the 6.4L.
I hope they are wrong, or I hope that an aftermarket turbo will be developed.
