Hey trying to see if there is anyone that is comfortable on the LS3 platform. We have a Oldsmobile Cutlass in the shop with a LS3 crate engine and E67 ECU. The car requires partial throttle to get it started up. Once started it revs to about 2000 rpm while still holding partial throttle and then the revs decrease and the engine dies out. Looking for an experienced tuner to get a base map done and fix the idling issue.
