The tuner made 91 ACN map. Stage 1. I know you have supporting maps but you have to listen to what your car is telling you. The maps are not custom and will not work as well for everyone. Your corrections happen because knock is detected. Knock is a very destructive condition. Cylinder chamber pressures during knock are much higher. High octane fuel is more knock resistant. The fuel in canada is not the best.
Run 91 ACN and see the difference. A bigger intercooler and down pipe are not going to compensate for canadian winter butane filled gas..
