Allright, I am going to upgrade my inj. to 42lbers and maf to a pro-m 80mm cal. for the 42's, kirban afpr and afm power pipe to finish up the v1 s-trim I installed last summer. I will get a custom tune and ditch the fmu now. Can I keep the stock in tank fuel pump and inline t-rex I have now or should I ditch these for a 255lph pump? All is stock on my car motor wise-no plans for a hci or anything else. If i need a different pump, where to get??
