That torque curve is deliciously flat but why does the dyno run only start at 4,000 RPM? What happens before that?

two things I heard.

1) Dyno wide band was off during this tune session. It was reading .7 to .8 to afr leaner than actual wide band in car ( Which was newer/ more reliable than the dynos )

2) The dyno has a special load function, everything was tested from 2,000 rpm on . ( different dynos load differently ) , The max power was a full run from 3,000 to 7400 rpm . produced 332 hp im memory serves me , but car was heat soaking..

3) car could use a hair bigger hotside or more efficient exhaust to carry that power a little longer, but that setup is fantastic all around.

looks good dude

Love the top mount setup.... Does it cool good? My buddy as a Vmount setup.
