How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

NHTSA investigating Ram 1500 models for rear differential failure

The National Highway Traffic Safety Administration is investigating Fiat Chrysler Automobiles and its Ram brand following a number of reports regarding the 2005 Dodge Ram 1500 pickup. According to 15 consumer complaints, the trucks' rear differential locked up while in other cases, the driveshaft separated at its connection to the diff.
Nearly half of the reports claim the truck was traveling at or above 50 miles per hour, while two consumers reported that the diff lockup/driveshaft separation sent their pickups into a spin. Most troubling, though, is that consumers reported little to no sound indicating there was a problem with their truck.
We reached out to Ram for additional information, such as how many vehicles may be affected or what equipment might be fitted that could cause the issue. Unfortunately, the company wasn't willing to elaborate on specifics.

Dodge designer on yellow plastic splitter guards: 'I wish they would take them off'

About a year ago, Dodge began placing yellow strips of plastic on the leading edge of Charger and Challenger front splitters to prevent damage during transport from plant to dealer. Dodge embossed "To Be Removed By Dealer" into the plastic, but those instructions weren't always followed. By summer of 2018, so many owners had left the tabs on, or reinstalled a discarded set, or bought a set on eBay for $100 or more, that factions broke out. Some thought the protectors looked cool, some thought they looked foolish, some thought it didn't matter either way. Now Dodge and SRT lead designer Mark Trostle has stepped in with his thoughts, those being, "I wish they would take them off."  Trostle made the remarks at the end of a video by Canadian auto scribe Brian Makse that otherwise dove into the design and technology on the 2010 Charger Widebody. Part of the designer's remarks related to aesthetic aspects — designers are paid to be precious about every line they draw, after all. "When we did the sketch for the Charger and Challenger," he said, "it never had yellow strips on it," and, "To me, as a designer, it ruins the lines of the car." He had a functional reason as well, though: "You're just ruining the paint!" The paint issue convinced Tyler Grant, the Internet sales manager at a Dodge dealer, to make a Facebook post in April this year requesting owners remove the splitter guards. Grant wrote that because the guards aren't specifically molded to fit perfectly, dirt and moisture get between the plastic and the splitter and mar the clear coat or paint, illustrated by a scuffed example that had been driven just 18 miles with the protectors on. He ended with, "Please, on behalf of your splitter AND its paint, take off the splitter guards." Despite forum chatter, splitter-shaming Facebook photos, and Facebook groups like "Hey Pal, You Forgot to Take Your Splitter Guards Off," it appears too late for the protector color to curb (get it?) the trend. Owners have already dealt with the dirt issue by putting protective tape on the air dam, others have painted the spilitter guards to match the car, and the owner of a vintage Dodge pickup ran yellow tape across the width of his front bumper in an attempt to join the party.  In the Makse video, Trostle said that the automaker would soon be rolling out a "new fashionable purple color" for the protectors. "We'll see if that one takes off," he said. "I hope it doesn't."
