those numbers are low for your mods.. the dyno is probably off or something.
what hp u dyno

At one of dyno days back in October of 2008, a bone stock MS3 on a dyno jet with 91 octane did 242whp. I forgot the torque. When I dyno'd, I came an hour early after driving an hour to the place and got 258whp and like 278wtq with an MS CAI and Forge BPV. Then my last 2 runs averaged about 242whp due to heatsoak.
On a Mustang dyno in our area, bone stock MS3's dyno'd at 210-215whp.

Ok..I guess my MS3 with an SRI and Forge BPV did pretty good on the mustang dyno.

They call Dyno Dynamics "the heartbreaker" because it doesn't give numbers as high as the other manufacturers. However, it's one of the most repeatable under varying conditions so it's great for tuning. They're also nice for high horsepower applications because of the way the unit cinches down harder as the power level rises.
When I dynoed my pickup truck on one, the operator told me to add 15% to compare to a Dynojet. Other sites suggest even more. I really didn't care, just wanted to win a horsepower contest they were having. I tend to believe trap speed more than dynos since there is so much an operator can fiddle with on the dyno, but the traps don't lie.

No it won't. Having a baseline run at the same dyno to compare to would tell us if it's good or bad. Chasis dynos aren't 100% accurate HP measuring tools, and there is a lot of variability in the numbers they produce. Everything from the way they simulate rolling resistance to the software calculations and environmental corrections they work into their calculations can swing results around in a big way. You could run on a Dyno Dynamics one run and a Dynojet the next and see a ~10% difference in your numbers.
Dynos are useful tools, but don't fall in love with the accuracy or relevence of their numbers. All a dyno tells you is that on this particular chasis dyno with these particular variables set to these particular values and with the temperature and humidity corrected for in this way this dyno calculates your hp/lb*ft to be X/Y on this particular day. You should be looking at a baseline run unmodded and comparing it to modded runs on the same dyno configured the same way for your car to eliminate as many variables as possible from the numbers, and use it to see how large a % increase you are getting out of your mods, or even as a tuning tool.
Numbers aren't really "good" or "bad", simply relative to your car, the specific dyno you're running on, and how the software and hardware are set up for your runs.
since your still on stock psi, u wont see huge gains with the dp upgrade. get tuned
hahaha, dramastically!
And?
