I installed the High Yield System myself in around 2 hours. The mounting bracket attached to the Peterbilt frame with ease and the installed system looks and works great. Thanks!

The guys at High Yield Performance installed an OTR Series 1000 on my 2003 Peterbilt with 1,250,000 miles in early December 2012. The system was easy to install and it looks fantastic mounted under the hood. I went from 6.25 mpg to 7.44 mpg by the 1st of January 2013. I was concerned 'only' about increasing my fuel economy and told the installers my rig had all the power it needed...Boy was I wrong! I instantly felt the increase power and I was shifting much less in the mountians. The systems will save me around $12,000 a year!

Running OTR Series 1000 is cleaning up the engine oil. The second oil change I ran over 7000 miles, could pull the dip stick and was able to read all the writing and oil level lines on the dip stick through the oil. This will be big savings on engine wear… I have seen a 1 to 1.2 m.p.g. increase in my 550HP Cat.

I turned off my OTR Series 1000 unit and my mileage went from 8.1 miles a gallon down to 6.5. Needless to say, the unit is back on - Thanks guys.
