By the way The AVO turbo kit and the raptor supercharger kits are not available for the 2015+, due to no tuning or fuel pump solutions
Thanks to XRT Ed, I have been given the confidence to move forward with the project. I live by multiple Subaru tuners, and was turned down by all of them. Ed said he was up to the challenge, and I like working with people that have a can do attitude

Now the car is running great. I have made some decent pulls to collect data for ED. He is doing an outstanding job!!! This is the first time anyone has tuned a 15+ NA for turbo and there are a lot of hurdles to overcome. ED is knocking it out of the park. Every time he sends me a ROM it gets better and better. His CVT tune is awesome, makes it feel like a sports car not a grocery getter.
