I heard back from Seb at Specialty Z, as everyone has stated he was very patient and helpful in answering my numerous questions. I inquired about HP gains and torque, his reply was very interesting and reflected a person with a great deal of experience. It depends on the health of the engine, fuel quality and mods to the car at the time of the tune. "Health of the engine", I would have never thought of things in that manner. He did say he typically sees 10 - 20 HP gains so obviously if a tune is done it is to improve the overall performance of the car as much as HP / Torque gains. The last question I asked was which Tune he recommended; Off The Shelf or Data Log? Considering the current mods on my car, no future mods will be done and the car will never see track time he replied the OTS tune would work just fine in my situation. Even with an OTS tune he still reviews the results and tweaks it a bit. OTS cost is $650. I hope this helps someone in the future. Thanks
