2010 ASA PRO-4 Champion
I have it on the 250 tune . just exhaust and tunner that's it. I notice a haze of black smoke when i just touch the go pedal taking off and if i put it on the floor a black cloud then goes away. Its starting to black smoke a lot more now and was wondering if its from the stock air filter? I have the K&N setup for it . The filter monitor shows about half way. Also if i put this in the 210 tow mode it shifts so hard feels like its going to break something. Its like doing a neutral drop in every gear up or down shifting that's how hard its shifting. Called spartan and the guy said that's normal? Any help would be good thanks. Forgot also the fuel mileage is gone down a lot. I drive it easy rarely do i ever go over 10psi of boost and it still goes good just want good mileage more then the power.
