I'm with you Jeremy! I swap back and forth between 3 engines according to many variables. I can't be bothered changing everything according to where I am racing. The two biggest factors for me are size of the track ( which directly effects run times) and whether or not it has huge short run up jumps which require lots of low end torque. Each of my 3 engines is specifically set up for the 3 tracks I race at most and all I have to do is drop in the engine according to the track I am racing and maybe swap out my shocks and sway bars and some minor tweaks. Your not alone bro!
