Dyno numbers

Guys, I have a 1994 Pontiac Firebird Formula 2.73 gear car. I just had my car dynoed today at South Ga. Corvettes. My car is pretty much stock except for a K&N air filter, carsound high flow cat, throttle body coolant bypass, and a Hooker aerochamber muffler. My car was dynoed on a Dynojet dyno machine. I made a total of two pulls on the dyno. My best on the dyno was 239.7 rwhp and
295.8 max torque. My car has 162,000 miles on it and still runs strong. My question is, is this a good dyno number for my car with the mods that I have. Thanks

You really need to post the whole curve to get a good description of the power. Just the peak numbers doesn't tell anywhere near the whole story.

The peak HP sounds good, the peak TQ looks fishy, like maybe you're measuring the AT converter spike rather than the engine's TQ.

I think it seems kinda low. It does have a lot of miles on it. A tuneup might help a little.
