I've got a question that hopefully someone smarter than myself can answer.
Correct me if I'm wrong, but it seems that most tuners ramp up boost (peak boost and boost throughout the power band) to achieve most of their power increases. I don't know what the average peak boost is on some of the 93 octane tunes, but isn't it around 22-24 psi? Now when I look at Gearhead, I assume they ramp up boost throughout the power band, but their peak boost is lower than that of most tuners (around 18 psi). So, are they focusing more on timing?
So which method of tuning is generally better? Lots of boost, or less boost and more timing? Or does it even matter?
