Your OBD2 ECU will still run them like it's running the stock 240s. You will run pig rich till you tune. You have to either get it tuned to run properly on 450s...or you have to buy an ECU with a specific program for 450s and your exact setup (yeah right).

Edit: I just read "resistor box". So now I'm unsure.

It's not listed, but I assume a FMU is present? At a lower psi, the stock 240s will hold. When you cross over to 7psi, then I'd look at upgrading them.
