Wait? That's stock? Lol no. Unless you have a print out I call bs.
I have cobra pipes, ram air, coil overhead ignition, no cat and was told by tuning guys here that this makes about 160 to 165 with a diy tune.
Unless you have internal work done a dyno tune is pointless $ spent. You should be doing the mods before you spend $ on a dyno. Last I checked dyno cost about $200 for an hour.
Please post results of your dyno.
Imo modding a rocket for power is pointless until you do internals because the transmissions on these 1st and 2nd gens are trash. Ask me how I know, I had 4th gear exploded one me. Common.
