Summertime is a great time for the lake, the beach, and the barbeque but when it comes to making power, heat robs turbocharged cars of quite a few ponies. We were happy to tune and hit the 400whp mark with a 2012 MazdaSpeed3 with a very clean and efficient setup on a mild E85 mix (30%) in the middle of summer. Looking forward to working with this Speed in the future once Mark gets additional fueling sorted and perhaps builds the motor. The current setup he has is a very good example of what it takes to get to 400whp in an MS3.
