Its a computer upgrade. Nothing more. In a 6.5 you will get a gain but nother like today's new diesels. If you throw in the computer, intercooler, exhuast, wastegate, and injectors THEN you are talking performance gains. Not too far shy of Alpha power, but its gonna cost you for all those litte toys. And on a stock headgasket your boost increase is gonna kill 'em sooner or later. Eventually you'll kill the engine, those mods will decrease the lifespan.
