I have contacted a number of CDI manufactures inquiring if they would offer an EFI performance CDI. All of the companies I contacted said no, one company even said never.
I recently contacted a company that came out with a CDI for the Predetor.
This is the response that I got back from Procom.

"As of this time we do not have plans to make one for that model. We will
produce a CDI Box for a model if we get requests for that same model from
various riders. If you know any riders with your model then please pass my
email address on to them and have them email me with the model and year that
they are interested in. We will make a CDI Box if we receive at least 20
requests. I will keep your information on file so if we do receive requests
we can add them to the file.
I believe that we have gotten requests for the Sportman in the past and will
be looking into that, but remember the more requests the better.

Email address would be cool. I'll fire off an email if it means that they'll make one.

 

there are no CDI's on EFI models, CDI's are for caurborated models. to get more performance out of your EFI, buy a PowerCommander from Dyno-Jet
