Hey Jay, it’s been a while since posting this but figure if you still want direct input, we use PSI as a supplier for a small number of engines and I work in the aftersales part of the business. While I don’t handle them as a supplier, I’d pass based off my coworkers that do. We’ve had significant troubles with obtaining parts that are PSI proprietary, for both gas and propane engines. We don’t use the 5.7 but that’s my input based on what we see. I have former coworkers that used to work there too and they have moved on as well.
