I am about to have pcmforless retune my computer with 42# injectors and on their tuning sheet they ask for what size injector and what brand of injector. I'm not sure what brand to tell him? Are Racetronix, Lucas, and Delphi all made by the same company? Can I just tell him 42# Lucas injectors

 

I'm pretty sure they're all made by Siemens now. They bought Delphi who I believe bought Lucas. Racetronix is just a distributor.

 

It's confusing, how they describe the brands
