Seems you have some cash flow for this project so there would be another device that works well. Wide Band O2 sensor... for many reasons. Main one is to see AFR not going lean under WOT boost! These ECM/PCM we have been talking about have no boost adjustments, so 100 MAP is what you get for all boost. That said they work fine for these small boosts and stock/mild motors. Would be plenty to push the Chalet around without making it a race truck.
Let me know what Wide Band you'd be intresed in and I'll look at the controller and setup. Some are very basic and stuck with 14.7 to 1 reading, others can be programmed for the E10 fuel at 14.1... either way making them read Lambda is so much easier and accurate. After all they are Lambda controllers converted to AFR...
Somewhere beyond stock motor your going to need more fuel! So an adjustable regulator is first step, for the boost changing the intank pump to a TPI or =early model Vortec is a bolt in. Pumps look identical, just have more flow and pressure.
Another improvement is a Boost Retard control for spark timing.
