This is something we have been working on a while. The press release is pretty self explanatory as to what it will do........and YES, it will support 1200hp with the upgraded injectors. But me personally, I consider this a retro-fit kit for street cars and mildly upgraded motors. This is similar to Atomic and some others, that you answer some questions on a touch screen and it is fully self tuning. You can NOT tune it yourself. If I have 1200hp I want to tune it myself and this would not be the system I would pick

Can I use a laptop if I want to do additional tuning?

Yes! BUT we recommend this for PROFESSIONAL TUNERS. FiTech is not a tuning school and we are not here to teach you how to operate laptop software. If you are a proficient tuner, you can do ANYTHING you desire with the laptop software including messing up your engine! If you are an amateur or even a well-rounded tuner you will have more than enough available at your fingertips, please stick to the Hand Held Controller. It is MORE than enough for 99.999% of users.
