Very nice setup! - I really like the AEM gauge. Do you know if they offer an IAT gauge with a similar type of sending unit.

The Boost gauge I used had a remote mounted sending unit. You ran a vacuum hose to the sending unit and then the harness to the gauge head. Not quite as clean as the AEM setup.

I ended up splicing into the dash lamps so the gauge would dim with the rest of the interior lighting.
