I like cheap stuff but,
If you research how much money you would need to invest on equipment and software to tune MB cars versus the amount of people who actually will have it done then you will see this is a fair price.
Unfortunately our cars are not fords in this aspect.

I had Anthony of TVT tune my crossfire and I purchased larger injectors from him.
I am happy with the power for the price.
I have not made it to the track with the new tune but the car definitely pulls harder from 3800 rpm and up.
I work on cars for a living and even my coworkers were impressed with the felt difference.
Just figured I toss in my $.02 in case it helps anyone decided if it is right for them.
