The 569 cams will give approx 10 bhp and 10 lbs ft extra torque through the rev range over the standard 548 cams with a Stage 1 set up. This doesn't sound like much but it is noticeable. They should to be done along with a free flowing exhaust, air filter and unlocked ECU with a suitable map. On their own they will not work well with a standard set up. The standard locked ECU and its map will run out of adaptive map range. Although it will run, it won't run correctly through the full range.
