I don't see where you mentioned what your current setup is or what your plans are. If you're running a bone stock CT-26, there is no advantage to an after market FMIC other than for the looks. If you plan on going with a bigger turbo and injectors, then by all means a FMIC will help you in the long run. Your decision to go through the headache of mounting a FMIC should be based on what you want to get out of it...routing custom hard pipes and hanging the FMIC itself is no walk in the park. Seeing you received both units for free, I would try and sell them and use the money towards the goal you want to reach. Neither of them look to be in good shape, so getting anything out of them might be a challenge, but there is always someone out there needing what others have. Good luck.
