Question on Hi -Altitude and FI Cars

[Pio]

With elevation, normally aspirated cars lose some power. I race at LACR which is roughly 2,600 ft above sea level, sometimes the DA worsens the effects. Anyways, a friend tells me that FI cars lose less power then NA cars. Is this accurate?

Yes, FI and nitrous cars will experience a much smaller loss then NA cars. At LACR my personal experience has been that the car usually runs 4-5 tenths slower NA and 1-2 tenths slower with FI.
