Improving 6.slow

[6.slow]

Yet more questions....

 

So, between Wait4me, Westerns, and others, do I need to change octane? We got 87 round here and if I swap to 91 or 93 will I really be saving coin by buying more expensive fuel? Can I get the same for a '98 GMC K1500? No fear of dealership concerns round here, our trucks ain't got warrenties no more. Do tow occasionally with the 2500HD, but looking to improve power and fuel economy on both. If we stuck with 87 octane, would it limit improvement? Looking for real live results... Both trucks run mud tires year round so freeway driving ain't much concern, but get up and go is. Love that low end grunt. (shoulda went diesel, I know...) Any help, advise, testaments?

Thanks.

Hypertech is your friend. My friends dad hooked one of those up to hid 2003 2500 and liked the resutls of 40 extra HP.

When I was getting my PCM4Less, I figured out that if I got 1 mpg better economy, the high octane would pay for itself. Just figure:

2.00 per gallon for 87 divided by 12mpg = $0.17 per mile

2.20 per gallon for 91 divided by 13mpg = $0.17 per mile

 

I actually am getting 13.5mpg now and was 11.5-12mpg before the tune. Some people here have had bigger increases. So I agree that it's worth jumping up to another tune.

That was funny!

In a 26 gallon tank, a "fill up" would cost you about $5.00 more for the Premium fuel. Even if you dont get better milage, you'll get better performance (with a tune only) and better fuel additives.

I run premium and i'm proud

I hate to be a party pooper but a higher octain tune won't do diddly for mileage unless you're at a constant WOT state. Crusing along at 55-80 requires no more octane than regular provides. If absolute maximum HP is desired then go for high octane tune but if the most cost effective option is desired go with the regular octane tune.

 

Normal Joe there is no way you can save money by using the most expensive fuel, the improvements don't equal much less surpass the increase in costs. But you will have more power. Since you plan on constant stop and go driving the power increase when accelerating may be worth the costs to you. But remember that it isn't a good idea to tow with a "hot" tune, you could end up riding the knock sensor and really loosing power and mileage anytime you tow. What I do is run a low octane performance tune and run high octane fuel when I tow. I have no complaints about milage, power, or towing.

 

As far as additives go you can't beat Chevrons Techron and they add it to all their grades. It's the only fuel I use and I've torn down a lot of my engines so I know it works. Chevron bought out Texaco and now they have Techron in thier fuel also.

Thanks, I only tow occasionally. But I'm one of those guys... Ya know the type, if you got 300 horses, better be able to use then if needed. Even if I never might, I want it all available. May never NEED a seltbelt, or airbags, but I'll never not have 'em... Most frequent towing is usually hay wagons and firewood. No rush or deadlines-except weather...

As far as the acceleration aspect, I like to give it hell once in a while but only at lower speeds. Thanks for the input and advise. BTW, I changed to 6.slow.
