Got Tune?

[jroller]

Just wondering after me and the guy I work with made some runs with our 2000 and 2001 PSDs. We have the same Summit 4"exhaust and Ive got a KNN with a filter wrap and hes just got an AFE filter. Both autos. This contest happened befor my DP F5 went in. For some reason I consistenly pull 1.5 to 2 Full truck lengths on his truck.
Could this truck have had a programmer in it when I bought it? How can I tell if its got a programmer loaded. If so I know you shouldnt stack tunes so should I be concerned about running the F5?

The f5 will simply over ride the programmer if there is one in there. It won't hurt anything. Without knowing for sure, there is no way for you to find out if your truck has a program downloaded.

Ditch the K&N, they cause issues on our trucks. Do the DIY "tymar" for about 60 bucks

Thanks for the advice but Ive got the external wrap on it so it filters even finer debris than a regular KNN. Plus its CARB legal and was already on the truck when I got it. Ive read all the stuff on here about KNN but Ive yet to expierence any reliability issues with turbos or MAF sensors with a KNN. Go figure? This is my 5th turbocharged vehicle and Ive run only KNN. As a matter of fact when I pulled the stock turbo in my Evolution VIII to replace it with a bigger one the the impeller blades look amazing, with no nicking or sandblasting after 60,000 miles. However if I, at any point, find that a KNN is adversly affecting my turbos it would be gone tomorrow.

its something with the drop in k&n filters not sealing right in the stock box on these trucks.(it might just be the stock box itself..) The full k&n replacement intake doesn't have that problem..

yeah the stock box doesnt seal well with any filter
