Ok, it a LS3 6.2L engine, same head castings as the L92 but the LS3 has lighter valves. Is that good enough. I have the L92's, I know the difference.
Ive got a set too,scratch that,I have the best flowing ported l92's available to the mass's.Yourself?

Its a difference graph, its easier to see the differences. It basically says:
FAST LSXR: 16.6 ft lb peak gain and 15.20 peak HP gain.
Ported LS3: 11.6 ft lb peak gain and 13.25 peak HP gain.
It also shows the FAST is up about ~10HP and ~10 ft lbs(on average) through the mid range(3600-5500 RPM) over stock LS3 intake. And ~5HP and ~5 ft lbs(on average) over the Ported LS3 in the same area. At the end of the pull both intakes are gaining over the stock one.
Does that help out explaining the 2nd graph and how to read it? Seems like everyone is concentrated on the top graph only trying to read between the lines.
haha, silly me.....when I read the post for the first time I saw the jumpy lines and quickly discarded the graph without really looking at it, thanks.
GM Intake has a 90mm cable TB
FAST Intake has the 102mm FAST TB
Wanted to use the 90 for both to better simulate the LS3 TB but after bolting it on, there was a small spot at the bottom where the larger intake inlet would not seal with the 90mm completely.
I'm pretty sure the MAF was a small restriction, just more apparent with the ported intake and FAST intake.
So the LS2 90mm throttle body does not work with this intake?
