Pass Racing Street Under drive 4ag pulleys instock

here is my feedback after my boss installed our under drive crank pulley,

my car set up: (pretty much stock)
HKS intake
stock exhaust
nology hot wires

so far i been driving with our under drive crank pulley for 3 days, all i can say is it makes my engine feel 6 years younger. i constantly shift at 4000 rpm trying to keep up with all the hybrids on the street for 2 years, after i installed the under drive pulley, i realize power kick in much earlier. instead of shifting at 4000 to keep up with the OEM crank pulley, i shift at 3000 - 3300 rpm with the udner drive crank pulley. this is more noticeable on 3rd, 4th and especially 5th gears. on the 1st and 2nd gears you wont notice of much power gain from the under drive crank pulley, but it creates much faster throttle respond than OEM crank, rev much quicker, and also when I down shift it pick up much quicker also(i guess because is much lighter weight and under drive than oem crank pulley).
