Tuning questions on EGT for N54
What's the temp on our N54 stock and after tune(13psi)?
Is the EGT cooler when using methanol? Is using higher octane decreases the EGT? Does leaner AFR results in higher EGT? Do we make more power at colder EGT or at it's peak? How can we lower the EGT? What's the ideal AFR for maximum power?
