My local shop gave me a High estimate of 150$ to install a jet kit I'm going to buy, do u think that's a decent price? He said he would probably only need it for an hr which they charge 100$ N hr and he said they might need to tune it up a little After. I am running a k&n filter with no box and hmf slip on . I think it runs fine now and I'm hoping i will notice a difference when I get the jet kit.
