Hi guys my first post so hopefully I can get to the bottom of this!

I have a 2016 fiesta zs 1.0 ecoboost with 30k miles and it's got a revo st1 remap, my car decides to have 'moments' where I won't have changed the fuel or have any different variations but it decides to suddenly be very very quick! Without over exaggerating it completely transforms into something else! using normal unleaded it will be quick doing around 0 - 60 in 7.1 - 7.2 seconds respectively, but then it will have a sudden 3 days where it just goes nuts and had the chance to do a run in this 3 days and recorded 0 - 60 in 6.9 seconds with my gf in car, it's not any sort of illusion and friends that have come in car have notices without me saying anything. It doesn't sound like a problem but would be nice if it could stay in it's crazy days all the time! 

Appreciate any help ! Thanks

    The system allows a certain amount of overboost, provided some variables are met.

    Ambient temps

    Inlet temps

    Exhaust temps (pre and post)

    Fuel temp

    Engine coolant temp

    Electrical load

    Are just some of the variables that are monitored.

     

    For instance

    My 1.6 tdci will be like a rocket until it warms up, then it dials the fuel and boost back to prevent overheats.

    It's a little different due to it being diesel but it's the same principal
