No, I have a relationship with those manufactures. Also, its a matter of choice and how extreme you want to go with the selection of mods. In my case I am extremely sensitive when it comes to mods on my car. Can it be done for less, of course, but I had
warranty and dealer tolerance to consider which affected my choice of mods.
What
bear-avhistory posted of the MSRP on the tune, intake, downpipes, FMIC is correct for most buyers. You can get similar mods for less, however quality, durability, performance, longevity and warranty does not come cheap and if it does it is more likely you will be compromising something.
If you lease then disregard all this and go the cheaper route. If your not keeping you car for long term then go the cheaper route.
My car is a build car that I am planning on keeping for years to come. This is my DD currently atm, 19-20 mpg on current tune. As on the track it performs on the street, no need to change maps
If there is another tune I would go with it would be the Cobb AP with a Protune
