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.

Dodge Scat Packages add Mopar performance upgrades in three stages

Dodge has revealed what it calls Scat Package Stage Kits that enhance the performance of the Charger and the Challenger equipped with the 5.7-liter V8, and the Dart equipped with the turbocharged 2.4-liter inline four-cylinder engine. The Scat Packs use Mopar performance parts that also can be bought separately. Most of the upgrades increase engine output, but Dodge somehow manages to not specifically mention the power gains associated with each Scat Pack.
The three Scat Packs offered for the V8-powered cars focus on higher power ratings, and each stage comes complete with a unique engine-management calibration to optimize output. Stage one comes with a cold-air intake and a cat-back exhaust; stage two adds a performance camshaft; and stage three really gives you the goods, adding ported polished cylinder heads and performance headers.
For the Dart, the Scat Packs focus on engine, transmission, chassis and brake upgrades. Stage one will net you a cold-air intake, a short-throw shifter and slotted rotors with performance brake pads; stage two adds a cat-back exhaust system and an engine-management calibration to increase output by taking advantage of premium-octane gasoline; and stage three adds 13-inch vented brake discs up front clamped by four-piston calipers, suspension with adjustable springs and struts and performance front and rear antiroll bars.

Continental Automotive recalls 5 million airbag control units

Takata isn't the only supplier having airbag problems. Rival manufacturer Continental Automotive Systems announced a recall of 5 million airbag control units fitted to vehicles from Honda, Fiat Chrysler Automotive, Mercedes-Benz, and even a certain Chrysler-based Volkswagen. This sweeping recall has actually been in progress for some time, although the exact scope is only now becoming evident. In October of 2015, Mercedes-Benz recalled 2008 and 2009 model year C- and GLK-Class vehicles because their Continental-made airbag control units could corrode. Such a condition could cause the airbags to deploy without cause or warning, or in the event of a crash, not deploy at all. You can read all about it in our post from last year. Now, Continental's recall is going wide. Alongside the already recalled C and GLK, you've already heard about the 2008 and 2009 Honda Accord airbag recall, which we reported on yesterday. Now, Fiat Chrysler is announcing the recall of the 2009 Dodge Journey, as well as the 2008 and 2009 Dodge Grand Caravan, Chrysler Town and Country, and their rebadged counterpart, the Volkswagen Routan. Yes, one manufacturer is recalling another manufacturer's vehicle. The models listed above only amount to about 580,000 vehicles out of 5 million bad airbag control units. And since Continental will notify manufacturers who will then issue their own recalls, it's extremely likely that more brands and vehicles will be ensnared. Stay tuned.
