He informed me about a pm3 which is a driver that take the load of the pumps and mimics the pwm from the fpcm so fpcm stays cool, and is able to maintain steady output bc it no longer carries the load, just sends signal. I obtained one and will install over winter. We will so how fuel pressure stays with it installed. He said it solved alot of issues for him. Also is able to run e85 and put down over 800+ to the wheels since adding this. Your my tuner btw [emoji6][emoji6] Michael Asher.
