[QUOTE=blktransam;7047799]well engines are ordered and should be here friday for this weekends race...ordered full mod for my truggy and race prep for buggy...is the full mod getting better fuel milage over the race prep as well? also what is the average run time also?

Thanks,
I was under the impression that you should run full mod in buggy and race prep in truggy because the modding takes away from the bottom a little and adds to the top. so in truggy you would want the torque.
