At this point, you have probably spent a good deal of money and time on your truck, so why should you have to hand over cash to a mechanic to do diagnostic work on your truck when you can do it yourself? This is the idea behind the Banks Power Programmer. Plus, because you probably do a lot of the maintenance on your truck yourself, hauling your truck in to a mechanic or service professional can be a big hassle. Banks Power Programmers are sold with many of the Banks performance bundles, but they make a nice stand-alone upgrade to your truck as well. Besides simply diagnosing any problems in your truck, these programmers can give you a power boost at the push of a button. This is done by synching up the fuel curve with the additional airflow; however, the additional boost of power is only tapped when necessary. That way, you preserve the life of the various parts that go into beefing up the power your engine puts out and also keeps your fuel economy reasonable. Banks Power Programmers can also be periodically updated so that its diagnostic capabilities are always up to date.
