If I put a juice, power puck or other device on my 09 will I have to change anything else? I am only talking about 50 hp +/-.

 

Not that I know of. Especally if you keep it on the lower settings

 

the '09's may go into a limp mode or shut down, if a programer is installed. the computer then must be reset by a dealer, at your cost. check around, several post on this subject has been covered.

The juice and puck are not down loaders you should be fine. Although mine would smoke like a coal train with the juice on hot and puck at 100%.

 

If I go with the juice or puck do I have to take off my blue tech stuff?

 

No you don't have to remove the bluetec crap, but it would be beneficial for you to remove it, save your truck in the long run! As far as putting a programmer on an 09, you need to check the build date of your truck, programmers may not work on your truck if its built after March of 09.

 

I took all the bluetec stuff off my 08 and ran a juice and loved it. I just don't want to mess with all that again but would like to increase the power some.
