Just type in ZFG tune in the search bar. 10 pages of stuff will pop up. Remember the IC by itself will not add any power, however it will allow for more aggressive tunes and make it easier on the engine when tuned and get the most out of the tune. Go to ZFG Racing on the internet. One last thing, this is a custom tune, depending on what you ask for, your tune will be different from mine. I asked them for 400hp to the wheels, Adam gave me 407 with the auto octane tune. While that only represents 50-70 hp over stock, the difference is amazing. As far as shifting, much smoother than stock because the tune programming adjusts the transmission for more precise shifting.
