Ok Thank you for the comments but I just got the TMAXX and it was broken in correctly and the problem just started the engine is great. I guess I should have said this in the beginning.

my thoughts are your engine is just plain worn out.everything you described are the symptoms of a worn out engine,and no amount of tuning is going to help.you need a new 3.3 engine.buy one off ebay.inseam

Traxxas 3.3 tuning help. by: Doug
Jeff, I would first check to see if the glow plug is not fouled or shorted out. If you are using EZ-Start are you getting a green light telling you the plug is OK? If not change glow plug. Next I would check for air leaks in the fuel pressure line and fuel supply line. If in doubt replace both lines. Are you cleaning and re-oiling your air filter?
If none other these things seem to be your problem, I would set the carb back to factory settings, go through breakin procedure again and tune the carb from that point.
