i was wondering which of these is the better mod. i currently have the jr and was thinking of adding the mp8 to it for added pressure- plus i hear its a great stack. but ive been reading that you can download the revo or the tnt(not sure) on the s-06 and have timing and pressure. which is the better choice? i know the mp8 has in-cab adjustability, which is def an added bonus. the smarty you can change whatever you want it seems. so what do you guys think? i know talk of the smarty/mp8 stack has been getting heavy, and talk of stacking the jr/mp8 has just started coming up. so whats your opinions? thanks..
