DIDNT WANT TO IDLE ON ECONO MODE

[LIMEPUG]

YOU DONE A GREAT JOB ON MY TUNER. IN THE PERFORMANCE TUNE I WENT FROM 15 TO 17 MPG. LOTS OF POWER. BUT WERE TALKING ABOUT A 2WD CREW CAB I THOUGHT THE MPG COULD BE BETTER. SO I PUT IT ON THE ECONO TUNE AND IT WENT TO MISSING AND WENT DEAD. I COULD NOT GET IT RUNNING SO I PUT IT BACK TO STOCK AND FINALLY GOT IT CRANKED. I WENT BACK TO PERFOMANCE TUNE ,RAN IT ABOUT A TWO WEEKS AND TRIED ECONO AGAIN AND AROUND 55-60 IT "BUCKS" A LITTLE. IS THIS NORMAL?

WELL NOW MY TRUCK GOES DEAD ON ANY SETTING. IT SEEM LIKE IT RUNS OUT OF FUEL.I CAN SWAP IT TO ANOTHER SETTING AND IT CRANKS UP. YOU MAY GO 2 MILES OR 200 BUT IT DIES OUT AND IT DONT MATTER IF YOUR GOING 60 OR AT A STOP IT WILL DIE OUT.

Return the truck back to stock and see what it does.

what truck is this?

If it works OK at first, it sounds like something is wrong with the truck, not the tunes...
