Reliable power is a lot harder to achieve than a lot of people think. Also, the majority of cars (and remember I did this professionally) come in on a dyno day on an empty tank throw in 5 gallons of C-16, wick up the boost on a ragged edge 12.5:1 tune and lay down a number, the owner then posts this up on the web proudly announcing his 550 rwhp daily driver. What they usually fail to tell you is that once that tank of C-16 is gone, the boost goes back down, the sane tune goes back on and the car puts out 380 at the wheels and that's what they are daily driving.
500, reliable, daily driven horses is a tougher goal.
