Lives up to the Sales Hype! Gas and Diesel both!
Programmed my 2003 Lincoln Navigator 5.4 liter engine after upgrading to a standard K&N filter (replaced the stock filter only), mileage went up 1.8 mpg after programming. Then used the Cortex Super on my 2008 Ford F250 Super Duty 6.4 liter diesel (you are allowed 2 vehicles for programming). Mileage went up over 2 mpg on the diesel. Unit was easy to update, easy to use. Pricey but worth it, will pay for itself in less than a year, especially with diesel at $4 plus per gallon.
good product and results after installation
Got good performance rusults after installation but had to contact superchips customer service a few times due to the update program not functioning properly. They were able to solve my error code issues but refered this programmer to my father and he had the same issues so expect to be calling superchips tech support. Other than that i average a 2 mpg gain and significant difference in power especially off the line. Autoanything was 100% perfect though. Look forward to many more purchases.
