  • 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.

    Titanium is awesome, though. Has similar corrosion properties to aluminum (in that it only oxidizes on the surface), is similar in strength to iron/steel, but is only about 60% of the weight iron. So it’s lighter.
    Plus if you mix in molybdenum and I think some nickel, you can have yourself a very long lasting spring that won’t sag like steel springs after several years.
    Main downside is it’s so expensive compared to iron :(
