I could be wrong but that looks a little low, can you post the dyno sheet?

Actually after looking at the dyno chart he only brought it to where it said it was getting max power he just set up the dyno chart to 6200 but it looked like it was still climbing pretty good

With a performance cam the chart is showing a 23% drivetrain loss IF you were still at stock HP?. That's not right for a solid motor. In the Charger forums they're saying 470 at the wheels with just a throttle body added too, but they do say this cam requires a lot of tuning.

Well I’ve heard upwards of 26~% drivetrain loss and the dynos I see online are all over the place some say 320 stock some say 390 stock which is a huge difference I asked him what they usually put down on his dyno he said 320ish but my only thing is I don’t think he pushed the rpms to there max we’re all done tuning it besides maybe one more just to bring the WOT a/f from 11.3 to 11.6 but he’s waiting for his tuner to make the final call I’m quite happy with the results if there making 320 stock on his dyno that’s 40 over with just a cam and intake trying to figure out now if I can do longtubes and still pass emissions in Massachusetts

Mustang dynos are known to be heart breakers.


The track is really the only good gauge


Then again running 11.3 A/F ratio on a NA motor is way too rich so maybe the tuner is not soo good.

OP who is your tuner?
