I have a stock f4i with a d&d slip on...I installed my pc3 usb and dont notice any difference. I chose a micron map with stock air filter since they did not have a map for a D&D slip on..in 2nd 3rd and 4th gear I sometimes have dead spots in the 3k-5k range..takes a second or 2 to build momentum. It usually happens right after shifting.. Do I use the buttons to make it richer or leaner in the low and mid range? Higher up in the rpms my bike is fine.. I cant change the map because I dont have a laptop and cant bring the bike to a pc yet...
I take it richer means more fuel and leaner means less or do I have it wrong?

correct.

and i'd take it off if your runing it on somthing other then a D&D map or dyno it for perfection.

 

i was in the same boat. with the d&d pipe and the commander. and i called the power commander ppl and they said just use the yosh pip map. so i did and it had the best preformance. i also had a question. how can i change it so i have more power in first gear low rpm.. say like 1000 - 3000 i would like somemore pull from the line?????

 

kewl, when I am able to I guess I will try the yoshi map..I think you have to make it more richer with button one, not sure though..maybe someone will explain in detail. You can go down a size on the front sprocket for more pull but then your speedometer will be off a little. I did it for a while but changed it back
