cant make custom tunes on edge
hey all i have an edge and i have a problem. i bought a used edge and when i try to make custom tunes on it it always runs like i have a cam and black smoke comes out my exhaust. i dont change anything that has to do with fuel or anything i just go in and change tire size gear ratio and shift firmness and it still does this. no one on the other forums im on can help me and AZFX4 told me to come ask here so here i am. any1 seen this problem? i have a 2001 with the 5.4
