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.

Chrysler investigating complaints of vehicles with faulty power modules

Chrysler owners are hopping mad after experiencing a series of electrical gremlins in some of the company's vehicles. Issues range from mere annoyances - windows rolling down and radios turning off of their own accord - to serious safety issues, with headlights that randomly shut off at night and cars that stall and refuse to start.
The issues are being blamed on the total integrated power module, which can cost up to $1,000 for customers to replace. This, of course, has led to a hefty batch of complaints to the National Highway Traffic Safety Administration, with 240 owners expressing their displeasure so far. Another site, CarComplaints.com, has registered over 300 complaints relating to the 2010 to 2011 Jeep Grand Cherokee and Dodge Durango, alone, according to The New York Times.
Chrysler has acknowledged that it's investigating the complaints and is analyzing the faulty TIPMs, but that isn't quite enough for customers of the affected vehicles. The newspaper has snagged a few of the more harrowing tales with the electrically challenged Chrysler products, culled from the NHTSA complaints.

Demon's NHRA competition ban: Good talking point, bad feature

One of the biggest headlines for the Dodge Challenger Demon is that, in stock form, it's so fast that the NHRA won't allow it to compete in the organization's events. It's the ultimate humble brag, "I can't drag race my car because it's so fast it was banned by the sanctioning body." Certainly Tim Kuniskis, head of FCA brands in North America, was excited. He told the press that he hugged the guy that brought him the letter banning the Demon from competition. Unfortunately, the reality is that not being NHRA-legal is kind of silly, and frustrating for owners who would want to actually race. Before we go too much farther, we should explain exactly why the Demon is illegal for NHRA competition. The car is capable of a sub-10-second quarter-mile time both on racing fuel and 91-octane pump gas. Cars that fast are required by the NHRA to have a full, certified roll cage, and the Demon doesn't. Now there are certainly ways to get around this. The most obvious would be for a Demon owner to have a company install a roll cage. Using less grippy tires than the barely street-legal Nitto cheater slicks would probably help bring that time down, too. There's also the option of putting the car into Eco mode, and, yes, the Demon has one. In Eco mode, the Demon makes just 500 horsepower, and trips the lights at the quarter-mile in 11.59 seconds, which will avoid the roll-cage requirement. However, none of these options are ideal. For one thing, if you bought an 840-horsepower car, you're not going to want to limit it when you get to a closed course such as a drag strip. Similarly, you're not going to want to ditch your super-sticky tires at the strip, especially when they're standard equipment. Finally, having to go aftermarket for a roll cage is an inconvenience at minimum, and it seems like a strange oversight considering the rest of the car. This is a car from the factory that comes with drag radials, no passenger seats, a racing fuel tune, air conditioned intercooler, and even skinny front wheels for drag racing. Its purpose is clear, but for some reason, Dodge stopped short of giving it a roll cage that would allow it to compete. Perhaps adding a roll cage would've made it difficult to pass safety regulations, and we would be more disappointed if the car wasn't allowed on the street. Even so, it seems like an odd stopping point.
