Yeah, that's 20% Nitro. The oil content in Top Fuel is 14% (I think). If you go much higher than that in oil content, it actually makes the engine harder to tune properly. When the truck idles, the fuel isn't pushed through the engine fast enough, and the extra oil sits in the engine. That's what causes it to load up.
Also, I agree with Six on the maintanence also. When a 2-stroke isn't running right, it's a little easier to narrow down the cause. On a 4-stroke, there are TOO many different things that can go wrong, making diagnosing the problem much harder.
