67 twin turbo dart

Sounds like the timing is severely retarded. I hate to say it but trusting your car at a dyno shop is a recipe for disaster.

True was just hoping to have it dyno tuned and be done but all the small bs came up. Well they checked timing and its to what I had set to on the computer, or if they changed it, since its the jeeps cam position sensor. Yeah always seem like something new, they build cars as well as do dynos. Have read where on the tranzact VB the torque converter pressure valve sticks, would this cause the same hard acceleration if the pressure isn't getting let out of the tq?
