  • Cobb Accessport V3 for Fiesta ST
  • One step colder spark plugs gapped at 0.025 - 0.026 (check gap every 5000 miles)
  • Stock Turbo
  • Stock wastegate actuator
  • Stock fueling


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 - 0.026.

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!

Can confirm, excellent tune! Very smooth yet very strong, clearly a step above flash e30 tunes! E50 makes for easy mixing for me since I get full percentage e85 year round, this can also make for a cheaper fill-up with max power for you guys who have e85 much cheaper than normal gas. I'm also seeing very similar numbers in vDyno, I'll update this post when I'm back on my personal computer with my chart...
