I would try some tunes from 5star for fuel economy. Check out there website it seems to me there economy tunes are set up not only to save fuel but help change your driving habits if you can't resist keeping off the gas pedal and all of their tunes are tow safe aswell.

For some reason our 'benevolent leader'(s) here in Kalifornistan don't trust us with the 'Demon Fuel' that is 93oct. I don't even think there's 92 anymore..
As far as 'chipping' is concerned, I've never installed anything (semi) permanent of this nature. I've always used programmers that allow you to remove your hot mapping, and re-load your stock tune. Ahh...the good 'ole days when you could load an HONEST +200hp whiz-bang map into your Duramax. I remember guys used to(and prolly still do) 'Stack' tuners to REALLY make their motor scream. Of course you had to strengthen your Allison trans to handle these Monster tunes, or you'd grenade your trans mucho-pronto. Neat thing about it was tuners like the PPE programmers gave you upwards of 7 individual maps ranging from 50+/-, to 100hp, 150, 175, and 200hp. Theyd tell you to not load anything greater than the 50 or 75hp unless you had your Allison worked over, but I always ran the 100/110 maps and never had any probs.
Anyway, I found a vendor on here named Brian Franchi, who gave me a good deal on an SCT, and even loaded a 'custom' mileage map for me. Like everyone else, I'll return it to stock when I take it in for service/repair. Knock on wood, but I've never had a service writer tell me they 'found' that I had previously loaded custom tuning, and thus were voiding my warranty. The Germans on the other hand, yeah, their ECU software reads various things like key/ign switch cycles to tell them whether you've uploaded/downloaded mapping and then returned to stock. My wife's owned BMWs for the past 9 or 10 years, and I've learned to leave those fuggin things stock, although at least at one point you could use Dinan mapping and it was either 'acceptable', or Dinan would cover you for any damage that BMW said the programmer was responsible for. Can't remember the specifics on that one, but no matter what you do to your vehicle, the burden of proof is on the dealer/manufacturer to PROVE YOUR MOD(s) caused the damage they're denying you warranty coverage on. Anybody thinking about doing any mods to their truck but are concerned about losing their warranty should Google 'Magnuson-Moss Warranty Act'.
