GM-Genius 120 Booster 3.7 - 7.4V
 

Anyone have any advice on the above for 1/10th OFF-road.

Any good??

Thanks in advance.

I 've got the one without the booster, and it has awesome power!

I am using it with a 10.5T on 2s and I 've got about, maybe even more speed than most driving a 6.5T.

I must say that I used the program on pc to set the speedo though.

Same here - conventional Genius 120 running a 10.5t and just as quick as 6.5t equipped cars. In fact its so good I'm running mine without the fan despite having the timing settings maxxed out and its still cool.

Thank you! :)
