The tuner I'm going to is reputable and has a lot of experience tuning road cars as well as race engines. I doubt he'll have an issue with it. I slightly adjusted the idle and cruise AFR targets so they get closer to what they're supposed to be but I'll let the expert correct the tables as I am way too inexperienced.
If your tuner can't make the car idle like factory, I'd get a new tuner. These injectors are fantastic and I'd have very serious concerns about a tuners skill set if they couldn't get them to idle well.
