I recently traded my f150 tuned by
php for a 05 F250 6.0. Well wouldnt you know the head gaskets were blown so warranty covered labor I did studs egr delete updated stc fitting and oil cooler with sct tuner. well hooked up my insight to it when it came out of the shop
ficm low 40v or 38v so I ordered a swamps 58v with the
php performance flash took it to my buddy at the dealership since I have no time lately and he installed it and also hooked into
obdII to check out a backup assistant problem said this has never happened to him before but as soon as he hooked in gave him a comm error then said cycle key once he did and then it flashed the
FICM and
TCM got it stopped before it took my
PCM so my custom tunes still work but now I wasted $150.00 on the performance flash

Just had to share my luck
