i wish i had the link but i cant find it right now but i can some what tell you about it on the FPR you will see a 3/4 brass nut you remove that and pull the spring out and place a 3/16 ball bearing or a bb from an air gun (that is what i used)in the hole put the spring back in and the brass nut and your done this inturn raises the fuel pressure but before you do this you must see where your pressure is because to much is no good you can do this with a tire gauge there is a valve on the fpr to check it

Shimming the FPR increases fuel pressure.

the results are worth the few minutes that it takes you to install the bb or cap screw. especially if you have no other chips or tuners. On that site that BadDog posted there is also a 10K mod on there thats worth the $1 for the resistor.
