Pump Gas

My daily driven “power adder” truck makes a shitload of power on California’s junk 91e10. Why do you tend to disagree with anybody that claims that?
Because my idea of a power adder car has a power adder for dragstrip/street racing performance. Most, if not all of those will have LOTS more performance on good gas, or e85, than they will on pump swill.
I consider a pump gas claim to be just another street racing lie/con job, or a drag racer bragging, USUALLY falsely, about making big power on junk gas.
Do you really think a guy with a turbo LS street racer is gonna run at 8 lbs of boost, 700hp, when he can put good gas in it, crank the boost to 15 or 20 lbs, and make 1200?
