But the real advantage of the MHR are their different stages and proven track record. Stage IV has some features you won't get with the PI tune and produces more HP...
Ideally you should have a "local" MHR representative in the US  |
I agree with all of your points with one exception. The shipment of the DME to a location outside of the US. I still have not been able to confirm the price of a new DME (not to mention what the process would be to flash this to your VIN) but any mistake or hiccup with the shipping would cause you a lot of heartburn.
