Thanks for that! Unfortunately my VT software says that versions of VT aren't compatible. I'm running version 1.12.
Were you able to open my log?
Would you be able to perhaps send a screen shot with rpm, vehicle speed, EGT B1S1, fuel injection amount desired and manifold absolute pressure?

The higher EGTs are normal when increasing power. It sounds like you're bouncing off of the EGT limits. I will work on a revised tune with slightly lower power.

Thanks Steve, yeah, I get that, more fuel, more heat. Its the dramatic reduction in power when it hits the limit, rather than maintaining the safe temperatures that seems to be causing the effect.

Look forward to the tune!

Thanks
Aaron
