I have a sparks full exhaust and uni air filter with box cover removed with plug in module. Im getting ready to install a 13.75 piston and cams (just wondering which cams to use?). Do i need to go to a power commander or will plug in module be ok?

with a higher comp piston and cams your most likely going to have to get a pim or power comander!! the best for motocross in the ltr right now is just to send your stock cam to ATP and you use the stock exhaust cam
