    There is no other MAP sensor option with the Sniper EFI.

    That would be great if you could post the numbers. Have you ever ran the engine without the ProCharger? And why is it under boost at idle? I think there's something wrong with the tune and not your MAP sensor.

    I'm running a blow through turbo/intercooled setup with Sniper EFI. I've been running this setup for over 6 months. No problems works great on 10 psi boost. Sounds like a bad vacuum leak. Also, with a ProCharger you need blow-off valve to be open at idle or it will pressurize while idling. This is my setup.

    Here's is a pic of my AFR. Notice on left side of page. I changed the vacuum & boost to be in middle of range. If I can help in any way, just PM me a I will give you my phone number.
