45 PSI is probably to much boost, it would be interesting to see how long the bottom end lasts with 45 PSI boost. Anybody know what the stock boost is my truck can hit 24-25 PSI stock. I'm not so sure timing changes won't damage your engine, back in the day we went to great lengths to get the timing perfect maybe advance it 1 degree on request.Thanks for the added information. We know that the small turbo is the limiting factor on these trucks. 45 PSI I'm sure turns our little turbos into hairdryers. That tune I'm sure would be great for a larger turbo swap on these trucks.
I sent you a DM as well. Look forward to seeing you more on the forums.
