On the Dyno

With just a handful of modifications topped with Jon Lund's custom tuning, the Trinity 5.8 approached 800 rwhp with the stock supercharger. As you can see, boost didn't increase much but the engine efficiency improved greatly. The final gains with the bolt-ons and fuel resulted in gains just shy of 200 hp and 200 lb-ft. How awesome is that?
