how would you go about tunning your car to get maximum peformance? is it hard? do you see a significant change? is it worth you doing yourself of should i bring it to the dealer so they can tune it?

 

get a performance chip... or a standalone ECU

 

This is why you buy an aftermarket chip. Performance tuning.

Otherwise, you would need a specialty shop to do a homegrown tune on it, usually only neccesary to go this route if you have a big turbo that there is no tuning for already. Most of the turbos (k04, gt2871) come with chips tuned for the specific turbo.

 

Its it worth chipping a 2.8

How much gain will you really get?

 

Read some of Rusty's posts on Passatworld and decide for yourself if self tuning is worth it for you.

Wow...

 

I looked at those k03 numbers. are those wheel horsepower??

You couldn't.

 

in my opinion no. since its NA you will only get a meager 10 or so hp...for a couple hundred bucks.
