Dyno runs today are pretty high, please take a look

All I took my car for a dyno tune today. The following are newly installed:


- E/C SC pulley
- PLM heat exchanger
- The new Bosch Intercooler pump
- New K&N filters in (btw comparing K&Ns with stock, I can see the K&Ns flowing better)


The humidity was about 50%, temp was 67 degrees


Jerry sent me a tune and as it was right on the first time with A/F hovering right in 12.0 and as the numbers were good we agreed it was pretty well dialed in.


I'll attached the image. The file he sent is only displaying horsepower. I've asked him for a screen shot showing A/F and torque as well (thye both looked nice and smooth).


So my biggest run had a max of 469 rwhp and 510 ft/lbs of torque. That seems awfully high. These are sae corrected. I do know dynos vary, yada yada...but still want to see your thoughts. A couple questions below:


- We ran this in third gear. I understand 4th is 1-1. if we ran in 4th, what numbers would I have expected to see?
- What gear do most people run in?
- What is our standard drive train loss on these cars? 20%


thanks all. I appreciate any feedback

Yup it's a DJ, also the reason Jerry does a 3rd gear pull on the DJ is because it prevents heat soak, a long 4th gear pull without ice will make iats go high
