I have a new T-Maxx 3.3 and it runs pretty decent most of the time.I've run about 12 tanks thru it including 5 tank Traxxas breakin procedure.It runs good ,but, gets too hot.I've adjusted the needles til it was really rich and it will get to the point it won't hardly run and I have to lean it back out to get it to run and make power.I usually get to a point where I think I have it and then it suddenly is too lean again.I couldn't get a infrared temp gun as they were out of stock.I do have a Venom onboard temp meter and that's what I'm using.I'm not necessarily tuning for a specifis temp I'd just like to find a way to keep it below 270 consistently and then work from there.
