Must bear in mind mate, when the boost level is raised this will be on a seperate map, which is only for 1/4mile or top speed to see what it can do.
Current power is for track and will stay at just that with an extra 1000rpm added. I have no intentions as yet to run anymore than 320ish on track as traction is spot on at this power.
Really can only be proven by taking a seat in the car, its surprising how that BHP number in a FWDcar can immediatly make people think its going to be wheelspin city.
