Ok, Heres My Problem I Set The Cruise At 70mph And Like 5 Sec. Later It Is At 67.5mph I Hit Resume /accel Button Once Witch Suold Set It Back To 70 But It Goes Back Down To 67.5. I Can Set It At 75 And It Will Drop To About 74. On Hills It Kind Of Surges And My Boost Gauge Will Build Up To About 8psi And Then Drp To About 3psi And Over Going Down Hill It Does The Same And Never Reaches The Intended Speed That Set. I Know The Fueling Modules Cause Surging But Mine Does It On My Timing Only Setting On The Xzt+
What Should Normal Vac. Be On A 24valve


Any Body Have Any Ideas?
