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 recalling 67k trucks with manual transmissions

Earlier this month, Chrysler announced the recall of some 280,000 pickup trucks over concerns that their axles could seize up. Now the automaker has announced an entirely separate recall of another 66,819 trucks over the springs that could break in the clutch ignition interlock switch. The recall affects Dodge Ram 1500, 2500 and 3500 pickups, as well as the Dodge Dakota and Mitsubishi Raider. The issue is relevant only to those trucks fitted with manual transmissions, from the 2006 and 2007 model years and manufactured between July 1, 2005, and July 31, 2006. Since a broken spring could, according to statements issued by the National Highway Traffic Safety Administration and FCA US LLC (previously known as the Chrysler Group) prevent the vehicle from starting, or cause it to move unintentionally once the ignition kicks over, the automaker will begin notifying owners of the affected vehicles just before Valentine's Day to bring their trucks into their local dealers to have the clutch ignition interlock switch replaced. FCA emphasizes, however, that the unintended movement would only occur "in rare cases" and only "if recommended starting procedures are not followed." Only one such case is known to have occurred, but it did regrettably result in a fatality. Statement: Clutch Ignition Interlock Switch December 29, 2014 , Auburn Hills, Mich. - FCA US LLC is launching a voluntary global recall of an estimated 66,819 older-model pickup trucks equipped with manual transmissions. The Company will replace their clutch ignition interlock switches at no charge to customers. An investigation by FCA US engineers discovered switches in certain model-year 2006 and 2007 pickups may be equipped with spring wire that differs from wire used in previous switches. The alternate wire may break and, as a result, the vehicles may not start. In rare cases, a vehicle may – if recommended starting procedures are not followed – exhibit unintended movement when its ignition key is turned. The Company is aware of one fatality related to this campaign. It stemmed from the single known accident involving this population of vehicles. The recall covers certain Dodge Dakota, Dodge Ram 1500, 2500, 3500 and Mitsubishi Raider pickups. Switches with the alternate wire were not used in any vehicles produced before July of 2005, or after June of 2006. The Dakota and Raider are no longer in production.

Chrysler recalling over 280k minivans because airbags may deploy on wrong side

Chrysler has issued a recall for some 2013 Town & Country, Dodge Grand Caravan and Ram C/V Tradesman vans built between May 10, 2012 and June 7, 2013. These vehicles may have a software error that would cause the wrong side (opposite side) airbags to deploy in a crash. With this defect, a left-side impact would cause the right-side airbag to deploy, etc.
The recall affects 281,500 vehicles in total: 224k in the US, 49,300 in Canada, 2,900 in Mexico and 5,300 in other locations. Chrysler will notify owners of effected vehicles, and reflash the offending occupant restraint control module to resolve the issue.
