Hello all I just got done building my LS4 and need some help getting it to run. 2008 GXP motor with the auto. Stock except for LS6 intake and ebay 102 drive by wire throttle body. LSXCELERATION
LSXceleration Stage 2.1 NSR Cam 218/227 .523/.523and Doug Thorly headers. Thanks everyone! It starts but won't idle at all.
