the Blitz SBCID boost controller. I was programming it. The units works very nice. I also have a FJO wide band with data logging for tuning on the road. I was going to tune low boost Less than 20 psi on the road to increase turbo response and decrease lag. Going to make a visit to the dyno for higher boost. I doubt detonation killed my engine. When I tear down the engine it will be evident if detonation was a factor. I think the bearing was on its way out and the rpm along with boost killed it.
