which comes first?
 

I am sure there is no wrong or right answer, but I will ask the forum for your opinion:

I have an 87T2 -with RP Bonez 2.5" downpipe and high flow cat. I also have a drop-in K&N filter. I like my car, and drive it pretty easy. I only wish to have ~ 50 HP gain, that is all (longevity of engine life is important to me).

The next upgrade I am planning is either the HKS EVC 4 or HKS F-Con PFC. The question is, which one should I install first?? Looking at some of my HKS older catalogs, one says the F-con should be installed first, another catalog says the EVC comes ahead of the F-Con.

Please state your opinion, considering the factors noted above.

And no, I can not affort to install both at the same time. :D

forget both, get a manual boost controler for $25 and get a apexi S-afc and a pair of 720cc secondary injectors and run 12psi

how much boost are you running now? do you have a boost gauge? thats the first thing you need.
