I wanted to add... I my butt kicked one day on the interstate by a fost. I had 4 people in my car and the dash said it was 97degrees outside (while going 80mph ). I saw it had a big FMIC has he ran up on me. But it was a fun little run, he prob put 2 cars on me. I had 3" tbe, AP3, and TT but stock besides that. Guy was cool, told me about a local facebook based group ( which was pointless cause I don't have a facebook).
Any stock turbo fist is gonna have a hard time from a 3Rd gear or higher roll against a focus with a bigger intercooler. Both our ECU's are very heat sensitive, but their intercooler is much more poorly matched in stock forum vs ours. Once they fix the intercooler problem, they have really nice power everywhere, then your advantage will mostly be traction based since most Fost can't control the power they have.
