Well, I was able to squeeze a few more WHP and made 508 WHP on my Mazda 3. I did some fine tuning as it was a little rich last time and getting right at 12.0 :1 A/F Ratio it made this power. This was still at 20/21 pso of boost. I wanted to boost around 24 or 25, but my wastegate spring is too soft. I will post the dyno sheet soon.
