shimmed fpr?

it actualy pretty easy there is a write up on how to do it. all you need is a bb and a 19mm wrench. the benifets are increased fuel pressure. which gives you a little more pop and better throttle response. and as far as i know no effect on milage. make sure you get a pressure guage weather is electrical in the cab or mechanical in the engine bay
