Disappointing Dyno #'s
I'll post the chart ASAP. The A/F was very good. It's a 6MT. Talked with a couple of other Z owners in the area and the consensus is that I am doing pretty good for this altitude(3000ft). I guess I should have dynoed before the mods. At least I've got my baseline now for future mods. If you had to choose the next mod: Cats or Headers ?
You're possibly running lean and timing is being pulled to prevent more damage to your motor from all the knock.
My '05 with basic ins and outs ran 15.0:1 on the wideband without reflash. That's very much destroy-your-engine lean. I feel bad for others that have more mods and no additional fuel. There was definite knock on my lean run and timing was being pulled like crazy to protect the engine.
I had my ecu reflashed and redyno'ed...Still leaner than desired...14:1 or so and slight knock up top. I'm sending it back in for a retune based on my latest dyno, but I made 265rwhp and 245rwtq w/ just my few flow mods.

Did 3 runs on the dyno and the best result was only 245 WHP. WTF !! I was hoping for at least 20 more considering that a stock 350 is usually putting down 235-240. Just wondering if my dyno #'s seem low or am I expecting to much from the mods. And what would be the recommendation to get the last 20 RWHP I'm looking for.
what's even worse is that the last gen mustang gt which only had 260 crank hp dynoed at over 230 we are being cheated!!!!!
the ones in the 220 rwhp range are possibly done on mustang dynos. They eat a lot more hp than dynojets because you're spinning the front wheel drum as well.
...and then there are dynopacks which typically dyno higher than dynojets.
