Absolutely. These type of motors can be very challenging. Especially if it is an automatic car. Most customers want a car that will idle on it's own without stalling. They don't want it to stall when they put it in gear. They don't want it to fall on it's face, hesitate or back fire as they accelerate from a stop. They don't want it to foul the plugs or make your eyes water from the exhaust. They don't want it to die every time they stop at a stop sign or run on when you shut off the engine. Etc.
I do my best to minimize those issues. Sometimes successfully sometimes not. Some compromises will probably have to be made. I'll be the first to admit they're tunners that are way better at this than I am. I do the best I can and try learn what I can to improve at this craft. The difference between a well sorted and tuned motor vs the same motor with a bad tune can be night and day.
