I've tuned a few 4 cylinder honda cars (turbo + na), a turbo nissan v6, and now my car (inline 6, turbo motor). My plan was to apply lean-burn to only vacuum loads, not positive boost load range. Under boost, It will be optimum for power safety (typically around 11:1 afr). Besides, when I press WOT condition I want speed :P!
I've read about some tuners "turning cylinders off" during light load cruising range as well. Does this mean they turn off the injector and spark to certain cylinders during each complete engine cycle? If yes, how feasible is it to combine this with lean burn? By cruising condition, I had in mind those road trips at constant speed/load (typically 60mph range)
