Ever since I put my new motor in the truck stalls in reverse. It also has some serious surging in reverse. Drive is fairly good. Rarely surges. Anyone that could help me get rid of the stalling in reverse would be greatly appreciated.

Motor is an LQ9, Edelbrock Heads, 11:1 compression, 224/224, 564/564, 110+4, 44lb injectors multec II injectors

On the scan it stalled at around the 10700 point. Also, if anyone has any ideas to make the truck run a little better it would be appreciated.

Thanks
Bryan
