1) No. The whole point of the Lexus upgrade is to avoid the installation of an aftermarket ECU or piggyback computer. It's basically a cheap and dodgy way of doing the same thing.
2) An adjustable FPR or RRFPR is recommended for fine-tuning, but it's not mandatory.
3) I would install a bigger pump for peace of mind. I'm not sure what the stock pump is rated at but you'd probably be pushing its limits if you maxed out the 550's.
4) Fuel cut will occur at much higher boost; over 20psi from memory.
