Well first off I have a RWD Silverado SS with a 6.0L with the following mods, 228R cam on 112lsa, LT's, CAI, exhaust, Vig 3600 stall, 4.10's. When I come to stops is starts surging really bad to the point where it almost dies. Even if I go in reverse it starts surging too. Any help/tips/ suggestions are greatly appreciated. I will post my tune and a log soon. Thanks!
