hey all ,could i get advice on which is best ,my rocket has the cat removed and a 3 into 2 system with staintune mufflers,on deceleration it pops and crackles like crazy. i have been told that a tuneboy tune will stop this and also open the secondary butterflies quicker than stock also re-calibrate my speedo and also turn my thrmo fan on at an earlier temp,is this true or a crock.so which is better.also what is the best coolent for the engine ,in the aussie summer i am finding the thermos are coming on soon after i set off on a ride.
also can i get some advice on other ,low cost performance mods i can do to wake this engine up a bit
