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.

Ram, Jeep redesigns on hold, Alfa Romeo models may come sooner

Last summer, FCA outlined an ambitious five-year plan that sketched out the company's product intentions for each of its brands through the end of 2018. However, even the best strategies sometimes need tweaking. According to Reuters after speaking with unnamed people at auto suppliers, FCA is now possibly delaying at least a dozen projects in North America for a variety of reasons. From vehicle to vehicle, these postponements allegedly last anywhere from just a few months to over a year. The sources from the suppliers claim that in some cases these tweaks are for engineering and design changes. The next-gen Ram 1500 reportedly has among the shorter delays and is being pushed from mid-2017 to November 2017, according to Reuters. Also, the much-discussed future Jeep Wrangler is allegedly moving a little later to July 2017. Among the vehicles purportedly seeing longer delays, the next-gen Grand Cherokee could get pushed back about a year to 2018. That then forces the launch of the three-row, luxury Grand Wagoneer to be even further away. Jeep's upcoming C-segment CUV and the all-new Chrysler 300, Dodge Charger, and Challenger might also see postponements. The one brand allegedly seeing an accelerated plan is Alfa Romeo. Without going into detail, the sources from these suppliers claim that the Italian automaker is getting even more vehicles for its lineup and could get them even faster than planned. "Those plans need to be flexible and fluid, with the potential to add some vehicles, pull some forward and extend the life cycle of others," FCA said to Reuters about all of these allegations. "We look at these programs on a vehicle-by-vehicle basis." Investment in the auto industry has been a major topic for FCA CEO Sergio Marchionne as of late. He believes consolidation is necessary so that companies aren't burning money on the same projects.

164K Jeep Cherokees recalled to protect liftgate from moisture

FCA is recalling 164,003 examples of the 2014 and 2015 Jeep Cherokee because moisture can damage the power liftgate controls on models that are equipped with that feature. Regionally, this includes 99,436 of them in the US, 13,195 in Canada, 2,406 in Mexico, and 48,966 outside of NAFTA. The problem came to light after the automaker started investigating a fire in one of the SUVs. There were no injuries, though. According to FCA US' research, the power hatch's control module potentially can be exposed to water. This can cause a short circuit and possibly a fire, as in this case. Until the issue is repaired, the company is advising owners to keep the cargo area dry on Cherokees equipped with this feature. To fix things, dealers will install a shield around the controls to protect them from moisture and will replace any modules showing exposure to water. Statement: Water-Shield Installation June 24, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 99,436 SUVs in the U.S. to install shields that protect their power liftgate control modules, and related components, from moisture. FCA US LLC began an investigation after learning of a reported vehicle fire. The probe revealed power liftgate control modules in certain SUVs may be inadvertently exposed to water. This may cause a short-circuit, creating a fire hazard. However, the Company is unaware of any related injuries or accidents. The campaign affects model year 2014 and 2015 Jeep Cherokee SUVs, but is limited to vehicles equipped with power liftgates. An estimated 13,195 customers are affected in Canada, along with an estimated 2,406 customers in Mexico and 48,966 outside the NAFTA region. The estimated total recall population is 164,003. All affected customers will be advised when they may schedule service. If the modules show signs of water exposure, they will be replaced. All recall-related work will be performed free of charge. In the interim, the cargo areas of 2014-15 Cherokees equipped with power liftgates should be monitored and kept dry. Customers with questions may call the FCA US Customer Information Center at 1-800-853-1403.
