05' Hummer H2 6.0L V8 with predator diablo tune install

[Hummer83]

When I installed the Diablo Tune on my Hummer H2 I got a check engine light immediately after the program uploaded even before I had started the truck. Code was for manifold absolute P0107...I cleared the code and have had no problems there after. But why is this happening? I had no problems with the map sensor before...I even replaced the sensor for the heck of it...reprogrammed pcm again with the Diablo tune and the same the code popped up. Truck runs great, light does not come back on after I clear it. Any ideas? Is this normal with the predator and this motor?

Thanks in advance.

Sounds like maybe a false code after the flash, if it clears and does not come back, no worries.

thx, whats the word on vehicles programmed with the diablo tune passing the emissions test. I live in Illinois and I got one coming up soon...I have a Air Raid CIA, with a 4'' down pipe after the stock cats...have you heard of anyone else having issues? They don't use the wand anymore to "sniff" hydro carbons....just an OBDII plug and scan
