How to get more power out of my Fiesta?

[GregJB102]

Hey everyone! My FiST is just an intercooler away from full bolt ons, and I currently have a stratified tune. Once I get that I want to get another tune to hopefully get some more power out of my car. I’m thinking of going with the Cobb stage 3 at first, but if anyone else has any suggestions for some aftermarket tunes that would be better I’d like to hear them. I would also miss the crackles from stratified so if their pro tune is worth it or if another company offers it then that would be preferred. Lastly, I would like to stay on pump gas because there’s not many fuel options near me. If anyone has any suggestions or horsepower numbers I’d love to hear them. Thanks.

You are better off with a custom/pro tune from any of the big names. Tune+, Stratified, JST, Freektune....there are a lot out there.

Just get stratified to do another tune, that'll probably be your best bet since you're already tuned by them. This thread has a bunch of stock turbo power levels. https://www.fiestastforum.com/threads/highest-stock-turbo-dyno-results.2755/

I'm very happy with Tunewerks. I got the "conservative" tune. Randy did several revisions while I looked for good 93. It rips.
That said, your tuner already knows you, and has a good rep. He'll do you right.

None of the Sheetz, or Wawa stations out there carry E85?

I haven’t seen any, but I could be wrong. Either way, I have a long commute to school, so I can’t count on it.

At full bolt ons, not much power is left aside from e85 and a turbo. Have you considered upgrading the snail? Do you have any specific power goals in mind?

Pretty much this.

I need to redo my 91 tune as well.

Hmm thats a little disappointing. I’m not great with doing mods myself, so I don’t think that’s something I wanna tackle myself, let alone the price is way out of my budget for the next few years while I’m in school. My accessport says around 227 hp when I use the hp gauge rn, and I doubt thats very accurate but based on that I think 250 is where I’d like to be (not whp obviously.) I’ll look more into other fuel options though and see if I can make it work. Would I have to do any other mods to use a different fuel type?

Update: Theres no way I could make it work. There are barely any near me, so unless I could also fill up on 93 when needed, it’s not practical for me at all.

You need different tunes for different fuel types. A good tuner (and that's impressive power in this heat) can do any E-whatever tune, and give you a 91/93 on top of that.
Add-on intake stuff DOES give you gains. Just not a lot. Even with the stock turbo, it helps. Looks cool, too.

Just do a 93 tune with your existing stuff.
If, for some reason, you have to use regular, just go to the Cobb 0 tune. That's supposed to mimic stock, and you'll be fine.

You can google e85 stations in your area.
