Once you have completed the break in cycle, you may begin tuning for performance. Make sure that there is a good smoke trail, that the engine doesn't sound like it's gargling the fuel, and that the temps stay between 200 and 250 F when warmed up and you will be fine.

Wide: Frankly, I can't understand people's obsession with not getting an inexperinced user to follow a "magic number.' I have yet to see an experience nitro enthusiast ask "how do I tune my truck." Therefore, steering those people who do ask that question to keep their mill at around the 250 mark just makes sense. Why would you want a noob to try and find the sweet spot anyway? The sweet spot is dangerously close to running lean when you are unsure of what you are doing.

Until you can tune by sight and ear, just use the 250 mark, making sure a good amount of smoke comes out on acceleration.
