The Osiris license is $300. We currently offer Osiris tuning for $495 in our area some of the other Nissan shops are around $600. We do multiple applications so we probably keep the rollers spinning more than some of the other guys. Re-tunes are addressed on a case by case basis. If the customer goes from N/A to boosted, thats a pretty significant change and will generally require another several hours of dyno time. Each tuner is different of course!
