    Yes the Tmaxx will be leaner than a Revo when the fuel is low.

    The Tmaxx fuel tank is the problem. The problem is when the fuel tank is full, the fuel itself is higher than the carburetor which leads to a richer setting. When the full tank is half full the fuel level is even with the carb, (this is where you should tune a Tmaxx). When the fuel tank is low the fuel is lower than the carb which creates a leaner setting. If the fuel tank is full when a Tmaxx is tuned for performance, you run the risk of being too lean when the fuel level gets low.

    Back in the day many replaced the Tmaxx fuel tank with a low profile OFNA tank which fixed the rich to lean change on the tune as the fuel level dropped.

    On the Revo the fuel tank is mounted lower and the fuel level itself (either full or empty) is always lower than the carb. This set up doesn't have the problem the Tmaxx does.

    Wait, so should I still tune my Revo at half tank, or is it okay to tune it on a full tank?

    Okay, good. That is what I have been doing as well.
