Going lean on manual shifts and let off
Going lean on manual shifts and let off First the specs:
66 Chevy C-10, 416ci, DBC, 02' Fbody ECU, stock LS3 heads, Holley high ram intake, 90mm NW TB, 42lb/hr injectors, 58psi at the regulator, custom 1 7/8 headers, Cam Motion street grind- 226/236 @.050, 598/598 on a 117lsa, Tremec TKO500 5 speed, ls7 clutch
The truck is running pretty good over all. I'm getting RAF and VE table dialed in slowly but surely. The main issue is the engine going lean on shifts and cruising when I back off the throttle a little. By lean, I mean pegging the gauge and misfiring.
Should I be looking at DFCO? If it's cutting fuel as soon as I let off the pedal will that cause it to go lean?
