Is there any other ways of fitting a boost gauge without having to drill and tap a fitting into the intercooler piping?
Found it... 1/8" x 1/4" so im on the search for one
I made myself a spacer for the Thrust/Boost sensor and tapped it off from there. Got the idea from here. There was a company who made a simillar thing.
Search and I am sure you will find plenty of information.
