I recently did a H/C/I/E/UD upgrade to my 07' TBSS. Every thing was working fine before the swap. Now as soon as I turn the key over the MAP fails which causes a chain effect of P0101 MAF Sensor Performance, P0106 MAP Sensor Performance and P0121 Throttle Performance. I swapped the sensor, swapped the TB back to stock but have left the MAF sensor in place. I adjusted all of the Electronic Throttle tables but those didn't do anything. The only thing I can think is that when I ported my manifold I cut out all of the insides. So there is no barrier between the MAP and the the open plenum. Could that be over loading the MAP? It is not the sensor or I have two bad ones straight from the store. Has any one else run into this or know what needs to be adjusted?

Thanks.
