We have seen very undesirable results with the oem spark plugs when developing our maps.  
One step colder plugs are a requirement on our tunes to ensure smooth operation.  We recommend NGK Part # 6510 spark plugs gapped at 0.025. 

You can buy these plugs at most local auto parts stores.  Please be sure to properly gap each plug as improper gap specs will create knock!

Tim is the 3rd tuner I’ve gone with in my time of owning a fiesta ST, and I can confidently say this his oem plus flash tune is by far the smoothest out of the three. He had it sent out to me in a matter of minutes, and I wasted no time to flash it. I’m currently running his 93, but I can’t wait to purchase his e50 flash as I’ve heard nothing but positive reviews from fellow fisty bois. 11/10 flash !!
