Basic Tuning: HELP!

Here is a link and it is really geared for all motors if you can weed through all the info. These are some great tips tricks etc... I found it cool since I used to tune the brand x with nothing but a vac gauge... http://www.diamondbackengines.com/technical-white-papers/vacuum-gauges/
There are several tuning tips on this site just look to the left in the tech section... Hope this helps and can clarify some issues you are having. Note alot of this stuff is geared towards radical motors but it will work with your motor as well... :D
