    Might be much later that a cutout would pick up power for a near stock LS1.
    her's my dyno sheets back when i had one of those things on my stock car with a SLP airlid.

    yes, it made more peak power. unfortunately, it made much less on the low and mid range. at the track, on nitrous, i lost .1 in the 60ft and gained 1 mph in the 1/4. overall gain et wise was .02. i took it off and went with the bassani tru-duals and picked up three tenths.
