Depends on the car. Tuning isn't some static deal. Each car is totally different, and each tune needs to be adjusted per car. The canned tune systems don't work as witnessed time and time again in the complaints posted in the forums.

Tuning allows you to make the motor run more efficiently. The more efficient the motor runs, the more power you make. If your car is dead to nuts accurate right now, then you gain a total of nothing. We rarely see that happen, 99.9% of cars we've tuned have made 3+hp across the rpm range, with more power being seen when there are drops in the stock curve. The more mods you make, the more potential to cause the stock tune to be out of whack and the more power gain potential you'll have.

Though some totally stock cars have made as much as 35hp gains, thats not what we're going to put on our advertisements. It's not fair to consumers to think that tuning makes that kind of power unless something is out of whack with how their car is running.

No car has ever lost power with our product. Remember we only make software allowing your car to be adjusted. We don't make power. Thats a byproduct of your motor running more efficiently. Most cars have a small bit left in them when they are totally stock. Cars with mods usually have rather large amounts of power to be made.

In fact if you look at the cost of an exhaust for the 370Z and the power it makes, vs. a full dyno tune with Osiris, you'll find that most of the time we're not just less than half the price but that you'll make more power with the tune. With the price of intakes right now we almost always win the price/performance comparison.

I'd contact one of our Pro Tuners if I was you and ask them some questions. Most of our Pro Tuners are very open and willing to explain details and work with you to plan out your mods so that you don't go doing something either very costly or totally useless. It's your money, and your car, spend wisely.
