I have an adjustable WUR and BL solenoid. I have the MSD box set for 4800 rpms.
When I give the car full throttle , at 4800 rpms I use to see my A/Fs go down on my wide band. Now I am running lean up top and don't see the A/Fs drop on my gauge anymore.
I checked the solenoid and it is working fine. I have a CIS gauge. Is there a way to check the WUR to see if it is working properly under boost.
Thanks John
