Secondary pump is not a requirement, but a nice precaution. I run E50 and with only the Walbro 535, I would see the low pressure side drop from high 90 psi to high 70 psi under Wide Open Throttle in higher rpm’s. Now with secondary pump triggered by Reflex plus, the low side never drops out of the high 90’s. Setup was a recommendation from my tuner David Shoup.
Looking good bro!! Keep up the good work! 👌🏽

Love the channel my guy. I own a 2013 BMW 535i Xdrive and I have some ideas. Would love to chat if you’re up for it.
Thanks for the support. Send me a DM on IG and we can talk. My IG is on the about page of the channel.
What do you experience that means a secondary pump is needed?
