umm,what do you mean not getting to full rpm?
track size not allowing it or the truck was topped out and was no more there?


if it was tuned for optimal performance then try swapping out spurs ,the rusty came stock with a 70t try a 72t for more low end grunt and faster take off but will not give you the high end that the 70t will and if you want more top end then a 68t will do that for you

Well the track was perfect for my car but when i was wizzin it up and down on a long straight i could just listen to it and tell it wasn't putting out its all like it isnt winding up all the way and no wheelies which i usally pull everytime i put it to wot so idk i was thinking about upping the spur anyways and i got tons of parts on the way so i will get them on and retune and everything

yeah just up your spur to a 72t sounds liek you were alittle under geared for the track and upping the spur will also give you more punch coming out of the corners too
if memory serves me correctly dumping 2 teeth on a bell is like bumping up 4 on a spur little food for thought
