Surprisingly not many. On my way to Denver there's no actual popping, but I have to yawn a few times to equalize pressure lol. On the way back only one ear usually pops, and that's not every time.

Update time. Had the truck ('19 XLT with Sport appearance, tech package, tow package, bed liner) almost 2 years and just hit 30,000 miles. Had a Livernois performance tune on it for the last 5,000ish miles. I have never reset my gas mileage meter. Over those 30k miles I have averaged 22mpg...

Didn't realize this thread I made took off like this lol. I ended up getting a Livernois tune for my truck, had it a while now and I am pretty happy with it. I tow a 19' camper a few times a year and it's no issues at all with it. They forgot to take the governed top speed out on mine so I'm...

Just got my tuner and downloading the stock tune to send in. Can't wait, anticipation is killing me lol.

Just got mine today. So excited lol.

Let me know how it does on 91 please. I'm here in the springs and have been seriously considering a tune for my ranger as well.

What fuel type is the JB4 tuned for? I can only get 91 octane here in Colorado, I haven't ever seen 93 out here.

I run 91 octane here. I'm not against flashing before I go out to do something, but isn't there a "learning" curve when you flash the truck? It learns your driving habits and adjusts for them and such? Or is this an oild wives' tale I have heard?

Do you have larger than stock tires? Are you driving aggressively? Like always heavily accellerating instead of slowly? I drive somewhat aggressively, but I don't have larger tires/wheels. I also only have the 4x4 with sport apprearance and not the FX4 package.

Just an update. Bought my truck in May, I now have 18,000 miles on it. I have never reset my fuel economy guage. During the spring and summer and fall I was averaging right around 23 mpg. Through winter, with having to use 4 high sometimes when there is a lot of snow, and a bit more city...

I am thinking of getting a tune, but I have some questions. Can you get it tuned so the performace increases are only available while in S mode? The reason I ask, is that this is my daily driver, I commute 55 miles one way to my office in Denver 2-3 days a week and a few times a year I pull a...

I'd like to get a tune for my truck, but was wondering if it's possible to only have it work when you have the truck in "S" mode. I tow a camper sometimes and have a long commute usually so I don't want to be putting the extra strain on the motor all the time. But at the same time, I do like...

How much time do you think would have been added if you were only running a tune with no other mods like exhaust, etc?

The camper is 2500 lbs dry weight, I'm not going to be loading much into it, much less another 5k in weight. Also - not a toy hauler. I've got my trailer brake controller wired in and working fine, as well as a new battery in the breakaway box. I'm not new to towing, I grew up on a ranch...

This is my only trailer, and my only vehicle capable of towing a trailer. Bought the camper and towed it home with no trailer brakes as I hadn't had time to install the controller yet, don't want to do that again, I was careful and only went 50mph the whole 65 mile drive back. I have to do...

Definitely not surge brakes, I will be picking up a brake controller and a leveling hitch tomorrow for it, thank you for that suggestion, Ihad never heard of one of those before. After reading through the posts it doesn't look like it's too hard to wire in the controller.

We are buying a camper this week, it's a 20' camper, and has trailer brakes and a 7 pin connector. The person I'm buying it from says that the battery on the trailer tongue controls the brakes, but I'm almost 100% sure that it's just for the breakaway brakes. Do I need a brake controller? If...

I was not in sport mode when I hit 110. I am rarely in sport mode actually.

I live in Colorado Springs and commute to Denver every day. I have city driving and highway driving, probably 65% highway. But our highways are not flat by any means. My commute over 55 miles starts at 6,000 feet, goes up to 7300, back down to like 6k, up to 6800 and back down to like 5800 -...

91 octane, 8k miles, avg 40mph puts me at 22.9 mpg. I'm more of an agressive driver too, highway cruise control set at 80, passing whenever I need to, treat stop lights like people are trying to race me a lot lol. Overall very happy.
