Next step was to blow compressed air into the vacuum line on the Hobbs switch....Nothing, nada, zilch. Took the adapter fitting off the Hobbs switch and found a clear sealant that was blocking the port hole on the Hobbs. Cleaned all that up, tested with compressed air, and boom Hobbs is now activating pump...Alright lets go run this back.

Go out make a 3rd gear pull with the M7 and shit... it's way out of fuel on E60. Low side is now dialed with the Cordes Aux setup but the high side isn't even close. +30 injectors are clear up in the 7's and rail is dropping way off. So I am looking at the log and see it's making 19psi of boost. I ask my Brother what pulley setup is on it and I believe he said 22% lower and 80mm upper which = Moon boost!

So this is what I know. +30 injectors, LPE pump, +32% cam isn't enough fuel for 19psi on E60 with a Heads/Cam/2650 setup.

Likely will need +60 injectors and a 44% lobe cam or Katech XDI pump system for this kind of boost. However I don't believe he was planning for it to make this much boost so he will be throwing a larger pulley on and will report back after we get it down to 16psi.

I will say the car is like a rocket ship until it runs out of fuel as is. Lol

I know I'm a broken record but per lingenfelter's tuner who looked at my logs assured me that an aux pump such as the dsx or smg won't cut it. He specifically told me they tried that route. Also 44% cam lobe will not fit through the journals. How ever the 42% will.

I got 880 on my 2650 on full E that's with the aux pump and 38% lobe but we also did a high flow line and ck valve which got us about 6 psi more low side under load probably about 74 psi until the low side fail off.

Tuner says it needs 80 psi under load which can only be done through return style setup. I believe the system cannot be setup this way according to Dave at dsx. After I told him I needed that psi.
42% cam
High flow line from pump, and ck valve

Only then will you get max effort from lpe stuff not that you need to run full E.. I was trying to setup something easy and idiot proof. A fill and go..
