Default My H/C/I Dyno
Mods are in sig. Not unhappy with the results, as the dyno is rather pessimistic (A Boss 302 Mustang usually puts down 376whp).

So a stock Boss 302 made 376 on that particular dyno?

Yep, he showed me the dyno, though I didn't see what the torque was.

I'll say it again, check the y axis scaling on the right (torque) side.

I will post up the y axis scaling, so you can see. It's extremely linear.

Come on guys, no comments on the new graph. I'm assuming it's flat enough.

Without seeing as much as the AFR and even the rest of the tune for timing curve we can't say much. Although doesn't seem that far off for a small lifted GM cam and shoddy Patriot heads.

The first graph had the afr. It's at a constant 13.4 - 13.6.

Didn't know patriot heads were that bad. I bought the car with the h/c/i setup. Thought the heads were better than dart.

I did not see that, but anyway. That's dangerous AFR and I'm not surprised if you have quite a bit of knock.

They're just 243s that were taken on by some dude with a dremel without any sort of idea or plan besides just hogging the **** out of the runners. Yeah they make flow air, but doesn't mean they have great torque making ability as can be seen by your graph.

Small cam, Patriot heads, and Slp headers with a crappy tune. Not really surprised with the results.

The results look normal to me.
Hot cam is small and not a huge power maker.
The heads are hit or miss.

Just putting in a basic 224 cam would kick it over 400rwhp.

Hp does not seem that far off to me. That hot cam is not big at all and like mentioned those heads are hit and miss.

Get you a bigger cam some 1 7/8 headers and a Fast intake and that thing should be well into the 400s with a good tune !
