• PlowSite Homepage Upgrade

    Hello again PlowSite community,

    I wanted to post a quick note to let you know that the homepage of PlowSite will experience a major upgrade next week. We’re always looking for ways to improve our users’ experience on the site, and felt that this upgrade was needed and long overdue.

    With this upgrade, you’ll now see the top trending posts as soon as you visit PlowSite, and these will be updated throughout the day. You can also easily access videos and photos. As always, we encourage you to include videos and photos in your own posts to share with your fellow PlowSite users.

    Be assured that all of the forums, content and data that you’ve been accustomed to will remain intact, as will all current site features. You’ll also be able to easily access the full list of forums directly from our new homepage.

    We’re excited to bring you this change, and look forward to hearing your feedback.

    Thanks, PlowSite Team

anyone using a hypertech programmer on a gas engine? Any big improvement as far as milage goes? 8-10 on highway is just not cutting it for me. Need to improve that some how.

You won't see any change in mileage using an off-the-shelf programmer. You might pick up 1 or 2 MPG if you get a professional dyno-tune, or a mail-order ECM upgrade. I can't think of any of the mail-order sites off the top of my head right now. The best way I've found to improve my highway mileage is to stay at 65 or under - it may take a few extra minutes of road time, but you I've gotten 16 MPG going 55 on long trips with my 5.7L and my 6.0L.

I disagree. I used hypertechs on all my previous 6.0L trucks and picked up an average of 2-3 mpg on the highway. I would average 16-17 on he highway @ 70 mph.

I don't notice a fuel increase at all on the diesels, but the fun factor plays in there :D

I used a hypertech programmer on my wife's S10 Blazer along with a cold air intake. I haven't noticed any improvments in fuel economy, but I don't know how to keep off the go pedal b/c it goes so much better now. I also went up in tire size and reprogrammed for tires as well. Did notice that on a long trip, milage increases a couple mpg's. The driveablilty is what really increased, even after a week, she noticed it and she doesn't notice anything when it changes in vehicles, kinda like men and women's haircuts.

ya... i know what you mean. I was once told this...
"if you go outside and push your truck across the parking lot it might be a little difficult, but if I help you push it would be a little easier."

I run one in my 6.0 with a CA intake. I only noticed 1-2 mpg better if that. I primarily installed it for pulling/towing. I drive it like an old granny and can only get around 12 hwy unloaded and around 7 plowing or towing. On long road trips, unloaded I can get around 13.
Either way it still all sucks but what do ya do when your in this line of business. You need a full size truck with a gas guzzling motor to get the job done. I can't wait for the new 2500HD Chevy/Gmc 6.0 hybrid to come out. As soon as it's released I'm buying one.
