You could get the aeroforce interceptor scan gauge for like $220 and it does a ton more than just the post intercooler air intake temp that your looking for. But for that to work you need to buy the extra kit on the aeroforce siteThis is what comes in it, I think its like $60. This is mine for my aero but haven't had a chance to install it yet. I want to do the same thing as you but am just to busy recently to get it finished.
