2o13 f150 platinum ecoboost misfire and limp mode

[robinsdt]

Not sure what's going on but whatever tune I use, the truck misfires and stalls upon acceleration and sometimes the gas pedal doesn't work for about 1min then it's ok. Dangerous! No check engine lights.

Help appreciated!!!

are you making any changes when you load the tune?
do you have the updated spark plugs?

Thanks

Mike, only change I made was tire size. I just ordered the spark plugs and will gap them and install. I'll let you know if it helps.

OK Sp534 plugs?
Gap to about .028-.030

Thanks
