I have been having a problem with erratic boost readings. I have been talking with Dave at SPA and he has been trying hard to be helpful. Everything worked fine for a few months then problems. Lighting quit and funny high boost,we changed heads.Boost still erratic, we changed sensor. Lights again and a new head yesterday. Still have erratic boost (sometimes spikes over 100psi.) New suggestion is to see if cable from sensor to gauge is close to any other harness picking up spikes of emi. Has anyone experienced any similar problems??



Thanks,

Jack,


I don't know how you mounted your boost sending unit but mine is mounted with rubber hoses at either end and it needed to be grounded to prevent the problems you describe. I stripped 6" of insulation off some wire, wrapped it around the sending unit, strapped it down with a band clamp and grounded it. Solved all my problems. Give it a try.


Good Luck,


Bob
