1 yr ago i bought an hypertech diesel programmer for my 06 f350 6.0. Ive noticed that my tranny shifted hard and i would have antifreeze spraying out of my overfill tank. So i bought the sct sf3 (powerstroke safe) tuner. My tranny shifted wayy better and i did not have any antifreeze leak. Then about a mnth in ive noticed that i got really ****ty mpg (12.5) and my antifreeze was leaking. sct sent me a custom tune to give me power and to supposely treat my truck better. Well now i have no tranny fluid and no antifreeze b/c this tuner eats all my fluids up. Then my egr valve clogged up. I now have my truck stock b/c i would rather have a slow diesel then a broken one. So im guessing tjeirs no safe tuner for powerstrokes. Has anyone else had these problems??????
