I run 315/35/17 nitto 555r for tires. It was about 45 degrees outside so a bit to cold for the dr's.
No problem.I may have to hit yu up for tips when my quarterhorse comes in. I have to tune mine and Im not familiar with this tuning software and hardware
No problem.
As for power made, I have no idea. The car is my nice day and weekend cruiser so it actually has never been to the track or dyno. Maybe one day who knows.
