Tuner Adaptability While on the Dyno
Every project is unique, so giving your tuner as many tools as possible to tune your vehicle will ensure you get the best result. Our Hybrid kit allows a tuner to decide mid-tune whether to run a Speed Density setup, MAF set up (with a more accurate air temperature input), or run a combination of the two depending on your specific application.
Why Would I Use this Kit Instead of Straight Speed Density?
The simplest factor to determine whether to go Speed Density or Hybrid is your current intake setup. If you have an intake with a MAF installed, we suggest going with the Hybrid. That way, you don't have an open MAF sensor sitting in the housing or spend extra on a part to cover the hole where the MAF used to sit. If you have an intake that doesn't have a slot for a MAF (IE most rotated turbo setups), then Speed Density would be the best route.
