On my return trip from San Antonio to Tucson I monitored my fuel mileage with the tune. Just west of San Antonio to about 50-100 miles east of El Paso I drove at 82 mph (speed limit 80 mph during daytime). Once it got dark I traveled at 72 mph until Tuscon where I ran into about 60 miles of 55-65 mph construction zones. After 900 miles of fairly flat landscape I ended up with 24.7 mpg. Not too shabby! Once I started through more mountainous landscape and up through the mountains east of San Diego the mpg dropped. After 1300 miles I got 22.5 mpg! Not bad for an almost 500 hp, 4200 lb car with a packed trunk, 2 adults, a two year old, and chihuahua!
Nice!! I knew I wasn't crazy. Nice to see the numbers on a longer trip. I'll be going to Vegas this week and keeping a close eye on it.
you guys suck I only get 19 on the freeway and that if I am barely on it. And my dumbass is thinking about a supercharger.
I call bullshit. This is all speculation and we have no definitive proof of Rick's MPG estimations... and I use the term 'estimations' loosely. I mean, he has a camera, why didn't he at least take a pic of his MPG readouts?!?!
I took a pic about two minutes after I called you at the 900 mile point. The cameras sitting on the counter in front of me. But, since I just drove 1300 miles, I don't plan on downloading it and posting it anytime in the next day or so. :stars:
That would be about a 2.7 mpg improvement, which fits with what others are reporting right? (Now where's the rest of the trip report?)
Pred Perf Tune. This was 900 miles across Texas, New Mexico, and Arizona averaging around 70mph. I did some test runs with my B&G while I was in Texas going to and from various places. I averaged around 22 mpg with that one. I love my B&G custom email tune and have it in the car right now.
Next week after my trip to the dealer for warranty trip (and I won't take my car in with anything but original backup tune in PCM 'cause I don't know how lenient my dealer is). I am going to run the same tests. 100 miles on my original backup 100 miles on 9R08 Perf tune 100 miles on RDP CMR tune I will post results for comparison.
