1,300 miles - 87 or 93 Custom Tune?
I have a PHP setup and have been running 93 since last Nov. Were leaving for Myrtle Beach next week and the Total Distance: 653.9 miles EACH WAY.
I havnt yet used my 87 custom tune yet but will this week to see what my MPG are or if it will matter. I just wanted to get everyones option would you use the 87 on the trip to save on gas since its so far or keep paying the extra $$$ for 93 the whole trip?
Thanks!

Thanks for the replies.
As stupid as it sounds I just cant make up my mind. The reason I got the 87 performance custom tune from BIll was for reason like this long trips and to save money. But on the other side Id really like to keep using 93 since thats all I ve used in 8 months. I think Ill try the 87 this week and make up my mind. Driving that far would probably save enough for a nice dinner while on vacation.
Then when I get home switch to 93 again.

On the canned tunes, I got enough better mileage out of 93 to more than offset the difference in price. After i got Bill's custom tunes, I have not compared to see if that still holds true. I ran a couple of tanks with his 93 Perf tune and then went to his 87 Perf tune. I can tell you that there is some difference in the two for sure, but the 87 is pretty awesome. Good enough to make me happy. It is better than the 93 canned tune. The only reason I have not run the 93 anymore, is I just have not been able to force myself to pay over $4.00 per gallon for gas when the 87 works so well.
I have a suspicion that if you kept records, you will find that the 93 Perf will still pay for the difference in price, which is usually only .30 a gal, around here.

Well this maybe apples and oranges but 2 weeks ago I took a trip with Troyer's 94 tune installed. I took this same trip a few weeks before I got the tunes, running 87 it took me just over 3/4 of a tank. This trip running the 94, driving style didn't change and it took just barely 1/2 a tank. The extra mileage more than offset the extra $10/tank.

Let's get an idea of mileage here. Are you driving in kilometers? Buying Imperial gallons? Paying in Canadian dollars?

With so many local and regional blends of gasoline, its getting very hard to gauge mileage accureately. E10 will reduce your MPG, some areas don't have it, some have the full 10%, and some only have up to 10%, which currently in my area actually means zero (I can tell they have not actually started putting the crap into the gas yet).

96L tank = 25.3 US gal.
So if it normally tanks me just over 3/4 of a tank running 87 with the modded parts on the stock tune, thats about about 72L or 19 US gal.
87 Octane on stock tune
317 mi/19 gal = 16.68 mi/gal
(72L/510Km)*100 = 14.11L/100Kms.
So going strictly by the numbers to fill the tank IF it was bone dry, using the prices I saw today this is what it would cost.
87 @ 1.375* 96L = 132
94 @ 1.481*96L = 142.176
Diff of $10.176. Now if I figure out how much fuel that would get me
10.176 * 1.481 = 6.87L.
(6.87L/14.11L)*100 = 48.68% of 100Km or I'd be able to go 48.68Kms on 6.87L of fuel.
94 Octane on 94 tune
317mi/12.65 US gal. = 25.05 mi/gal
510.2Km/48L = 10.62L/100Kms
(6.87L/10.62L)*100 = 64.68% of 100Km or I'd be able to go 64.68Kms on 6.87L of fuel.
I would do a bit of driving once I arrived instead of filling up so I would usually get about 575Kms hwy/city per tank stock before I'd have to fillup.
With the 94 tune I didn't have to fill up until I got to 710Kms so getting an extra 135Kms out of the tank more than makes up for the price difference.
Now these are just going by the numbers and not taking into account any external factors like accel./decel. , wind resistance etc...
Wheeew...ok all that math has given me a headache.

I'd make the trip using the 87 octane tune. That way you'll have figures to compare. If it's not as ecnomical, a trip like that will not bankrupt you, but you'll know for sure what's best for you.
And, if it does better (and you don't miss the "power"), you'll be golden.
Just as an aside, on a trip, you are mostly cruising - minimal starts and stops and, if you're on an interstate, you don't have to put your foot in it to pass (at least I don't). So, I don't really know why you'd want a "power" tune, unless the efficiency is so much better that you still get far better mpgs with the power tune during cruise.

In California, we get ethanol at 5.7%.
With so many local and regional blends of gasoline, its getting very hard to gauge mileage accureately. E10 will reduce your MPG, some areas don't have it, some have the full 10%, and some only have up to 10%, which currently in my area actually means zero (I can tell they have not actually started putting the crap into the gas yet).
Troyer wants to know if you have 10% ethanol in your gas.
In California, it is 5.7%.
I called the California Air Resources board and was able to locate this information online.

ETHANOL As a Transportation Fuel In California
As of January 1, 2004, California completed a transition from methyl tertiary butyl-ether (MTBE) to ethanol as a gasoline oxygenate additive. With most gasoline sold in the state presently containing 5.7 percent ethanol, California is now the largest ethanol fuel market in the United States. About one billion gallons of ethanol are expected to be used in the state's gasoline supply in 2004.
The Energy Commission continues to study the potential for ethanol fuel production and use as part of California's overall strategy to assure adequate transportation energy supplies and reduce dependence on petroleum. In addition to its use as a gasoline blending component, ethanol can also be used as E85 (85% ethanol, 15% gasoline) in flexible fuel vehicles being produced by automakers.
Most of California's current ethanol supply comes from the Midwest U.S. corn-based industry, with a small supply contribution from foreign imports. There are only two small producers of ethanol in California today; however, a number of projects for expanded in state ethanol production are under consideration.

ETHANOL (also know has Ethyl Alcohol or Grain Alcohol, chemical formula CH3CH2OH) is a liquid produced mostly via fermentation and distillation processes from sugar and starch crop feedstock. Advanced processes for producing ethanol from agricultural, forestry and municipal wastes and residues are under development. Ethanol has been used in the U.S. as a gasoline octane enhancer and oxygenate since the 1970s when federal energy tax policy was enacted to encourage domestic production and use of this fuel.
