    I am almost positive I have a boost leak, or at least something is wrong with my turbo. Stock on a WOT pull onto the highway, my car only pulled about 15.2 psi, while my buddies ST pulls about 24. I'm also losing a lot of torque (obviously if I'm not pulling the right amount of boost). But any...

    I purchased and installed a new FMIC, the Mishimoto 4.3" intercooler, and just want reassurance that 10-20 degrees over ambient air temps are normal? I stupidly forgot to use my accessport to check it before I did the install but I see people here with similar setups only seeing temps about 2-5...

  4. COBB Tuning
    I've finally finished putting on most of my parts and I would like to see what my numbers are and then see what I can get out of a tune. Already have the Cobb stage 3 map on it but I feel that there is still room to grow.

  7. Focus ST Performance
    I drive a 2018 Focus st with about 42k miles on it. I haven’t done many upgrades aside from minor appearance stuff as well as a sound sympose delete and an injen cold air intake. A couple days ago I purchased a COBB Acessport and plugged it in and mapped the OTS stage 1 tune. Car is running fine...

    I have a 2016 Focus ST and I have the Cobb AP set up showing my actual AFR, on idle it’s reading normal between 14.2-14.7 but once I start moving, different gears and rpms haven’t seemed to show any difference, it will consistently run 14.2-14.7, on occasion it will drop to 12.5 but from what I...
  9. Focus ST Performance
    So I just finished the 45 days available for custom tuning from mountune, got 3 revisions and still getting negative corrections. Randy, suggested I just use slot 4 (panic mode/1.5 degrees less spark) if that seems to run better. If not I can get another revision with even less spark. It just...

    I installed my AP today on my 2013 focus st. I am on the stage 1 93 octane slot and my car is making 23.95 psi and is backfiring when I get into boost at full throttle. It feels as if there is power loss when it backfires. It feels very un natural. Any ideas of what this could be?
