I installed the Cobra Slip on last week and today was the first time out riding since the install. The sound is great and I like the 2 into 1 look, but I feel like I have lost some power in the bottom end of 1st and 2nd. There is also some crackling (which I expected) and backfiring when decelerating. I am now wondering if I need a FI tuner, but I have not changed the air box. What are some of your alls thoughts on this?

Lots of threads on this one already. When I had my slip-on without the auto tuner it popped pretty bad. Since then I have installed the Cobra Auto Tuner and air intake. Great sound and power through all gears now with minal popping.
