I got a 2004 GT with 3500 miles on it. All stock except a K&N air filter and the air silencer removed. It still has the original oil in it (changing it this weekend). I put down 226.32 HP and 260.89 ft/lbs torque sae corrected. Is this good, bad or average? I will post the graph tonight when i get home from work. BTW this was done on a dynojet.

This seems a little above average. A stock auto should dyno around 208 rwhp (20% power loss) and a stock manual around 218 rwhp (16% power loss). The K & N filter should add 1-2 rwhp. There is some debate on whether or not removing the air silencer adds any horsepower. I read an article that said that the best gain came from shortening the air silencer rather than removing it. Maybe another 1-2 rwhp.

Thats what I was thinking 01mgvert...I was a little disappointed in the torque number though. I think I saw a couple stock dyno runs with the torque at 270 not 260 Maybe my engine is still losening up.

Numbers in my sig are completely stock, paper filter and dealer oil too. Dyno graphs are in the link. Your numbers seem on the high side of average, I'd give you 3-5rwhp from the filter though.

Here is the my actually dyno graph. Let me know what you guys think. Anything jumps our at you as being different? Any ideas on why my torque is at 260 when I was expecting it to be in the 270 range?

My 2003 dynoed 237/278 SAE completely stock with the MRT H-pipe as my only performance mod at the time. So I feel the MRT pipe definitely helped. I could also really feel it in the SOTP.

Numbers look good and are right on from what others have posted. A/F looks really good - nice and flat across the board. Congrats, now you can start modding with that baseline.

Looks nearly identical to mine, even the slight dip at the very beginning and then again around 3800. Good luck with the modding

You will pick up a bit more power as you approach 15,000 miles. I've recently become VERY skeptical of the K&N air filter. I replaced mine with a Fram paper and had a noticible performance improvement.
