Read thru some of the tuning guides in that link... just know that 4 tanks is usually not considered fully broken in , it can take as much as a gallon of fuel before that's all done, but you are ok to start tuning a bit after 4 tanks.... any further questions feel free to post them up as well as a few pics of your truck too....
I'll get a few posted up in the pic thread. This is my second nitro but I been out of the hobbie for 6 years. Thanks for the link and I'm sure questions will arise.
