Recently had the MSD 400 upgrade carried out, never noticed it before, but my boost gauge doesn’t appear to be working anymore. I’m going to take it back to the folk who installed it but was wondering if anyone has come across this before? Any thoughts before having to make the 180 mile round trip appreciated.
I should add I also had the Mountune recirc valve, high flow air filter and induction hoses fitted at the same time. Sadly no induction crossovers to be had, no surprise there!
