Ok guys. I want to make my FiST stage III in the next 2-3 months. It's bone stock right now. I would like some recommendations on which brands of upgrades I should get. The Cobb Stage III kit is nearly $3k. Can I save money be piecing together my own kit from multiple brands? I don't want to go cheap and sacrifice quality but if I can make a stage III kit from multiple sources that's just as good as Cobb but for less money I want to go that route. Thanks
I read the thread and seems how most of the response was garbage I just went back to your OP.
Yes, you can use parts other than the Cobb parts with the Stage 3 OTS tune. No, you don't need a filter, charge pipes, or a full exhaust. Depending on where you look you'll have conflicting data/opinions, but an improved FMIC and DP (or FMIC and CBE, depending on your sources) can yield pretty much maximum Stage 3 OTS power. 'Stages' on the FiST is basically a joke and only really a way for vendors to sell parts or for members to give a quick summary of their parts installation.
There's lots of data on the FMIC, DP, and CBE options for you to research and formulate an opinion. Outside of using two of those three parts (FMIC mandatory) you're not going to get much of any ROI at all. I wouldn't worry about having the absolute biggest FMIC or buying the most expensive of anything and concentrate on finding the best fuel along your normal usage.
I would strongly consider a custom tune though, even if you went with the most expensive or best (they're not the same) part for everything. A good custom tuner will extract what he can based on what you have and I've seen FiST owners that have achieved really good power with just an FMIC and quality fuel. Ymmv.
