Tuning methodology questions My car is being dyno-tuned next Friday. I am going to run a 78N jet. SCR is 11.8:1. Stand-alone is @ 60 psi with Klotz 118. B8EFS plugs @ .030.
What is the proper method to modify the NA tune when tuning with the nitrous? Obviously, you take away timing and jet the fuel side fatter than where you think you'll end up with to start.
Do you add timing in first and leave the fuel alone?
Once the timing mark is right, then start going to smaller jets for the fuel?
How much bigger of a fuel jet should I start with vs. where I will likely end up?
Where should the timing mark be when on the dyno vs. a full pass? How much closer to the threads will it be on a full pass?
Thanks for the advice.
