Here's a quick rundown of how we feel is the most efficient way to modify the Focus ST. If you have any further questions about the platform or Stratified drop me a line.Looks like a re-flash or a tuner to make the necessary changes would be an inexpensive way to gain decent hp and torque, any input or advice would be greatly appreciated.
Yes quite a bit. There are things to think about if you go that route: driveability, your use for the vehicle, cost, etc. If you are interested in tuning and want to be able to keep your warranty, then tune early with a FRPP unit from Ford Racing or a Mountune unit (look at their package deals for best value). Solid tunes and loads of fun without a lot of headache and butt hurt from $$$$'s. If you want to get creative, then Cobb AP3 or SCT, or now even HP Tuners make good units for us. Plus there are a lot of great Custom Tuner vendors in the site that can help.
this is my personal car oem tune vs stratified tune. This is with the oem tune at -1 OAR (aka as much as it would make on my specific car). Take note of the pretty substantial gains in midrange power as well
OMG will it ever!
