Folks, we have real results from our trip to Atlanta this past weekend.
Some background. We took almost the exact same trip last year when we went to Chattanooga. Same route and even got fuel at the same location. We ran the trip last year at 65 MPH on cruise control in economy mode at got 7.2 MPG had calculated.
We put in the Ultrapower C7 chip last week (XC-R chassis) in our Damon Tuscany. We were loaded the same way (three day trip) on both trips and pulled the same toad both times.
The trip to Atlanta this past weekend we averaged 8.6 MPG hand calculated. That is an increase of 1.4 MPG. This trip we ran at 63 MPH with the Ultrapower chip set on 15% gain. We also used a bottle of Diesel Kleen in the tank at the same time. We filled up at Exit 2 in GA on the way up and filled up again at the same Flying J (even the same pump).
Overall mileage sent up with the combination of the Ultrapower chip, Diesel Kleen and 3 MPH slower. Cannot say which was more important but we did see the increase.
As for power there is definitely a boost from the Ultrapower chip. I noticed it the most on the hills between Macon and Atlanta on I-75. On the trip last year the coach dropped into 5th to make it up some of the hills (we let cruise do the driving). This trip we never dropped into 5th gear at all and noticed that it kept up closer to our original speed.
Overall I am very happy with the Ultrapower chip. We will eventually make back to purchase price and am looking forward to the performance boost next month when we head to Niagara Falls.
Oh yeah, the MCU's ROCK! Worth every penny.
