Hey All Any help would be great.

I got an 02 f4i and between 3-5k it surges? Anybody ever have this experience. I got a slip on, dont know if i have k&n air filter, i would imagine stock. I have noticed that when i add a small amount of fuel injector cleaner or fuel additive to already 91 octane its goes away. i havent gotten a tune up yet, could that be the problem?

any clues would be great....

Thanx!

 

My bike surge's at around 3krpm if i give it too much gas. I have a slip-on and K&N with no power commander. I'm hoping after the PC it will smooth out a bit.

 

Mileage? Last time the plugs were checked?

 

i've got 28,000 mi, i dunno when the last time the plugs were checked. Think thats an issue?
