if I read the post and the tutorial right you are trying to remove the carrier's limit on interceptors correct? If that is the case, download the Carrierx2 mod from my signature and place the MPQ that comes with it in your Starcraft directory and open the Carrierx2.exe. Just ignor the Carrier's speed, that just something I added to the mod. I only made it for the Carrier, not for the Reaver.
Hope I helped
