You are The Hermit
Prudence, Caution, Deliberation.
The Hermit points to all things hidden, such as knowledge and inspiration,hidden enemies. The illumination is from within, and retirement from participation in current events.
The Hermit is a card of introspection, analysis and, well, virginity. You do not desire to socialize; the card indicates, instead, a desire for peace and solitude. You prefer to take the time to think, organize, ruminate, take stock. There may be feelings of frustration and discontent but these feelings eventually lead to enlightenment, illumination, clarity.
The Hermit represents a wise, inspirational person, friend, teacher, therapist. This a person who can shine a light on things that were previously mysterious and confusing.

05 Subaru WRX (EJ25) with DBW throttle conversion, FMIC, HKS 3037 turbo, HKS EVC 5 BC, fueling mods, AEM. Stock head and cams. Short block rebuilt using stock pistons, rods, bearings etc. Chart provided by customer; recorded 350 whp @ 1.33 bar. Fixed the dip in torque at the upper range.
Some quick calculations to validate the observed data:
44 lb/min of air is needed to produce 415 bhp.
Assuming intake air temperature is 40 degC, VE of 97%.
Therefore required MAP pressure is 44 * 639.6 * (460+104) / 0.97 * 3200 * 151.25 = 33.8 psi absolute, or gauge pressure of 33.8 - 14.5 = 19.3 psi. Or 1.33 bar of boost pressure.

Here is a dyno chart of an JDM 9 MR GSR that was tuned on Saturday. Mods are open pod intake, 2-3/4" exhaust, cat delete, EVC boost control set at 1.4 bar tapering to 1.2 at peak, and ECU reflash. Figures are at wheels. Take a close look at where the peak torque numbers are generated... if the accelerator wasn't let off so early it might've made peak power at 6500 RPM.
The other interesting thing to note is that this car makes 240 lb-ft of torque, at wheels, from 3500 to almost 6500 RPM, or almost 43% of the usable rev range. Not too shabby.
Oh, as for the link to the Best Motoring vid, it's hosted on Youtube here.
