Das Geld 2

I finally went ahead and did this as this was eating me up and I have been wanting to do this for the longest amount of time.

Here is the Dynograph we used the DynoJet machine
My Car is fully stock with no tunes 93k miles now. I need to do an oil change in 150 miles and my spark plugs have never been changed. I'll be debating a tune not sure if I really need it.




Here is the video:

Thanks

those are great numbers!!!

Quadcammer

While those numbers are good, they are uncorrected. The standard is an SAE Correction with a smoothing of 5.

Ask them to convert to SAE for you.

Good numbers and probably a little optimistic, should get around 240-245 BHP once corrected.

congrats on great numbers! Love that flat torque power band!

It's near sea level no need for correction as its people with high altitude in Colorado or AZ correct it to sea level. The reason for my dyno is because I beat multiple cars the same night who I thought had 30+ HP on me etc.

Quadcammer

not quite

The sae correction accounts for temperature, barometric pressure, elevation, etc.

The reason shops use STD or uncorrected figures is to make the owners happy with higher numbers.

Sad reality... Happens a lot!

You guys are probably right

Is this tool sufficient?

I got .0976 Correction factor

Dropping to 255

Quadcammer

probably close enough.

numbers are still good

"Lines on paper" are interesting, but the real proof is how the car performs.

Obviously, Das Geld's car puts a big smile on his face, and that is what counts!! Don't be upset with corrected numbers. I have seen so much variation and manipulation with dyno numbers that I don't take huge stock in them as the definitive performance answer.

Tuning will help your car and put a bigger smile on your face!
