No offense taken. No worries.
This is an important part of the equation. Most tuners will pull the pulse width down on top end to prevent over spooling the turbo / excessive soot on a all out tune. All of the trucks which we have seen with 205/75 can over fuel a s366. I'll see if I can get Busby in here. He ran this combination on his for a while with several tuners.
My personal truck does have a race tune on the PCM that has been live tuned. Additionally, I am pulling PW down via custom FICM tuning to prevent a lot of the excessive soot only because it is more effective to adjust the fuel MAPs of the engine using the module which is designed to hold the fuel map rather than the PCM.
For those who are familiar with our tuning, I am running the 200X pcm tune on a modified 'Economy' FICM tune.
If I were to advance the fuel maps to the 'herc 100' setting, I could easily over fuel my s366 across the power band while holding 4.9v ICP.
If I have the ability to over fuel with the PW fully open, yet still having the benefit of greater atomozation from the smaller nozzles, to me it sounds like the perfect combination. To each their own though.
