Angry No Boost after Anti Lag Install - 05-07-2019, 12:43 PM

I have a 2010 BMW 535i. It has a dual cone intake and was running a JB4 with the appropriate MSD back end flash for the JB4. I tried running E85 with map 5 but started having misfires on multiple cylinders. I installed a Precision Raceworks plug and play ignition and, at the same time, installed the JB4 anti-lag kit. I then restarted the car and the misfires were gone however when I test drove the car, it had virtually no boost. Under extremely heavy load it would generate 2 or 3 lbs of boost. I then inspected the install to ensure I reconnected everything and that I connected the anti-lag wire to the right pin location. I was unable to identify any obvious problems. I then tried upgrading the JB4 firmware to 32/14//2 and tried test driving it again. There was no change. I tried changing to map 4 but everything seemed to drive the same. Any suggestions on what I should check or what to do next?
