Not that I regularly blast the car to the red line but I’ve noticed my 250 doesn’t actually rev trough the redline. It bounces off the limiter just before at about 6k rpm. Looking at 250 acceleration videos on the net I believe the rev limit should be about 6.5k rpm? Anyone any idea what the problem could be? To clarify it’s not the cold start limiter as the car is fully upto temp when I try this.
Yes indeed, a stuck open thermostat means car won't get warm enough to get off the cold map - hence my reply but then I re read and you said it was fully up to temp?! If the water gauge is always low or drops down when you let off the throttle it's likely this is your culprit
Well I say upto to temp but thinking about it it’s mostly on the line before half way which I assumed was normal?
