I had my car dyno'd and tuned back in February. It has a naturally aspirated 3.5L V6. The tune bumped peak crank HP from 288 to 306 and torque from 254 lb-ft to 278, which is on par with the 3.7L variant of my engine.
While the peaks only gained 6 and 9%, respectively, other areas saw even bigger gains. For example, below 4000 rpm most of the power band gained 15-20 lb-ft over stock. And above 4500 rpm, the torque continues to rise rather than plateau which I've noticed in hard accelerations.
Another interesting thing is how much smoother the power band is compared to stock.
This was a bit pricey, though, and I see why most people don't do this often. All told, it was about $2500 to do: Pre-Dyno inspection, HP Tuners ECU, set of step colder spark plugs, putting it on the dyno, etc. Honestly, would do again and would like to do in the future.
Those are great numbers. What vehicle?
It's a Ford Taurus, so the engine is pretty common since they put it in just about everything: Taurus, Edge, Flex, Exploder, etc. They also have a bored version that's 3.7L. Those were in the F-150, Mustang, and some Lincoln vehicles.
So this tuning info could be useful to a wide range of people.
I forgot to mention that the tune uses regular 87 octane. No need for premium to hit those numbers.
Those are very nice numbers.
It's all about the area under the curve and you have definitely increased that area throughout the RPM range.
