Ford Focus rs bug

hi guys loving the game but have found a little glitch with the Ford Focus rs. When you equip the 1.6 rally motor and then go for the top engine upgrade it shows a max bhp of 497 but even on the screen then jumps back to the standard level for this engin and when in game if you bring the telemetry up it shows a bhp of 399 or if your lucky you may spike 400 but no where near the 497 which is a shame as it seems to suit the car quite well. Other than this so far the game is worth every penny and I’m glad I went for the ultimate bundle as I having been off the game since lol.
