Your car likely has between 155-165 rwhp depending on dyno conditions. The mods will add around 10 rwhp with a decent tune.

Umm....no it doesn't, it has 193 bhp, meaning hp off the flywheel, you loose 16-25% of the horse power to the rear wheels, less for manuals, more for autos.

http://www.v6power.net/dyno/

Here is a good V6 dyno database. Just look at the 99-04 Mustangs with similar mods and the same tranny. Depending on the dyno you'll dyno between 165 rwhp 185 rwtq, to 185 rwhp 190 rwtq.

Believe it or not the lower numbers are more accurate as they came off of load bearing dynos (hydrolic dynos), AKA heart breaker dynos. Higher reading dynos are more often inertia dynos (dyno jet) and or electric.

I was going to say they came with 190 hp stock but you beat me to the punch
