Like I said your charge air cooler is out performing but you padded it on a spike. Looks like your cooler has a larger thermal battery and near the end of the run there was not such a significant difference in temperature alone. Just observations.

I spoke with our engineers regarding the data, and they explained a few things to me.
First, like I said before, this data is real world data, and was not altered in any way. Many programs have smoothing factors / filters built in, so they eliminate spikes that are outside of the STD deviation. This is why Winpep has a smooting factor for dyno graphs. This data does not have any filters applied to it.
Second, the lower the sampling rate, the more drastic the changes will appear.- i.e. a 100/sec sampling rate will appear to have a smoother line than a 10/sec sample rate.
Third, the cause of the spikes is due to a mixture of hot and cold air coming through the intercooler. Because of the mixture, the sensors are reading the changing temperatures, showing a spike in the data. Try looking at our data applying a smoothing factor yourself, and see the average. The spikes in the data are not anything to worry about, but rather the average cooler temperature that our cooler provides.
Hopefully this clears everything up, and let me know if you have any other questions.
Thanks,
