getting bored of the stock output and am looking for substantial power gains.
any advice/tips would be great.

That's a very broad question. What are your goals? Budget? etc..

Like mentioned above search, you are not the first one here interested in making their truck go faster

 

Intake, exhaust, headers, tune is what I would do to start.

If you are looking for substantial power like you mentioned, a new cam and higher stall converter should make you more then happy.

 

substantial power?

Boost

 

/\ And theres always that...

 

Yea we need more info. Are you looking to spend $1000 or $6000?

 

Substantial power? Positive displacement supercharger or good turbo set-up, and either one with a good custom tune and be done with it. You have a good transmission with that 6L80 so no problems there. Boost will give you exactly what you are after.
