From my search on here there is conflicting info. I have a 73mm c&l with the proper calibration tube for my 90sc. Some say u need a chip or tune to run this and other say throw it in and it will be fine. From my experience on my mustang it was plug and play with proper cal tube. Thanks in advance.
 
Are you changing injectors? If not and you have the right sized calibration tube for the stock injectors you'll be ok, but not optimal.

If you are going larger injectors up to 42's, its not perfect and will get you by, but ultimately to get the most out of it you need to get a tune. Above 42's.... forget about it.

Send me a pm if you want more info etc on a chip-n-tune.
