67 twin turbo dart

No that’s a good deal. And I’ve dealt with VS a few times and he just did the twins for my boat. Great guy. BUT if it were my car I certainly would not spend another dime on parts until I knew the set up in the MS was dead on. It sure sounds to me like you have an issue in the software.
That's what the guy at the dyno shop is thinking too, maybe I'll just have them checked and check with diy to see if they can it the ecu out as well. Just to cover all bases.
