    Did an update a few days ago and cleared out the date log that took up most of the memory. I already picked the things I wanted to monitor. No matter if I’m sitting still or driving nothing changed and some of them don’t even say anything. The temp forever says 60. It was 23 this morning and at...

    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...

  5. 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.

  8. 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...
  10. 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?
