Ok you have an exhaust brake not a jake brake. As for your tunes controlling that I do not know.

all that does is change the vanes in the turbo. i dont think you can turn it up but it will run with the custom tunes

i had eric set a tune up for me utilizing the jake function. living in the hilly northeast, comes in handy when i need it saving from riding the brakes down hills. its basically an improved tow/haul function (cutting compression at certain speeds only), IMO and is obviously nothing like you would think it to be. something youd hafta try i guess :dunno:
