Dyno Result, need an expert please!!!
Hope this is a healthy number after dynoing the car with 2K6E55 today. I told the tech to do the run on 4th gear, cheers!

That is a beautiful flat torque curve!!
That run was done in 3rd gear not 4th... Your torque reading is a bit on the low side, but it might be due to the operator's method of engaging the run.. He might not have gone WOT quickly enough with his foot and he also started the run a little too late.. You should be starting the runs at 2,000RPM..
Jangy: The second line is SPEED. It shows MPH.. You can see the dyno plot shows a 50mph - 124mph run.. That is 3rd gear. With a stock ECU, 4th gear wont get you past 5,400RPM so doing it in 3rd isnt too bad.
All in all, your car is very healthy!!

When HP does not equal torque at 5,250 RPM, there's
a problem with the dyno report. Your printout show the crossover at around 4,800 rpm, so something is off. You need to speak to your dyno operator about the calibration on his Dynojet.

No, the chart is OK - HP and torque are equal at 5250 RPM. The issue is the plot scales - they are not the same.

Look at the vertical axis on each side - they are different. Go straight up from 5250 on the X-axis until you intersect the torque curve. Then trace over to the right to the torque axis - it's about 410 lb-ft. Now do the same for the HP curve and trace to the left - it is about 410 HP.

I'm so lost but if it's a healthy number then it's all gravy. I guess the K&N filters and snorkle tube didn't gain much.

Those are mods you'd only see on the butt dyno. HAHAA!!
She smells good to me. Anyone comment on the "dip' right at about 4750 rpms? Is that just normal peaking or could it be slippage?

Again, at 5250 on the X-axis, the value of each curve on its respective Y-axis is the same, as it should be. Only if both axes have the same scale will the crossover point be at 5250.
