compression
Why is it said the lower the compression the better for FI cars? I'm building a gsr block with ls internals and I'm coming up to the piston purchase. I hear different things like the lower the better. I want to go with 9.0-1 and a friend of mine is runnign 10.0-1 on his ride. Is there a hp difference in the ratios?

posts like these make people dumber. I award you no points and may god have mercy on your soul
Here is a brief advantage/disadvantage list of purely low compression vs. high compression. Don't let this be the end all, do your own research and figure out for yourself.
<FONT SIZE="2"><U>Low compression:</U></FONT>
Advantage:
Lesser forms of fuel can be used (Ie: a little higher numbers on pump gas)
more tuning error is allowed
Disadvantages:
Creates less power in the whole RPM range(about 3 to 7% for a full point of increase)
<FONT SIZE="2"><U>High compression:</U></FONT>
The opposite of low compression
Don't be scared about the tuning part. Even people with 11.0:1 and higher have turbo cars. It just needs a good tune to it that is precise and the fuel in the tank is proper for the power output. It's that simple.

You weren't wrong, just way too overgeneralized and then some n00b thinks this is absolute truth and nothing else matters......and there lies the problem
