Does the pulley make a difference? I've heard everything from it being awsome, to not being worth the money. Did you install it or take it to a shop? If you took it to a shop how much for install

took it to a shop and he charged me $50 cuz i know him....it does make a difference not a significant gain but you can definitely notice throttle response one thing is the gas LOL i was going to put in 2 gallons of 100 octane but i forgot to damn...

It is a lightweight/underdrive crank pulley. I put some on my 1.8T in the past. It lightens the rotational mass on the engine thus letting your engine rev up easier and quicker. For a turbo car that means you will be getting into boost faster.

Many people don't do them since the crank pulley may or may not act as a balancer for the crank (depending on the opinion of the day) and may cause wear/damage issues. Most people that have run them have not had any problems. You will feel like the engine gained some horsepower due to the faster revs.

seeing im under warranty, not touching engine parts that could possible void my entire engine

AS If *flashing or Chipping* doesn't do that already ????

and Lowering... and just about anything .....

They cant void your warranty for lowering or anything that doesnt effect the engine directly. a chip is usually not traceable so not a whole lot to worry about. just but it in stock when you got to the dealer. the pulley might be more noticeable

Just to answer some of the other questions, yes the pulley should make a significant difference. The drawback to an underdriven pulley is that your AC might not be as cold and your battery might not charge up as well due to both the AC compressor and the alternator not rotating as fast (usually 10-20% less). Some companies make just lightweight versions that are the same diameter as the originals so you don't have that problem.
