So haven't ever used this before. I'm sure it might be me or the truck? Went to write the first tune and loads 2 screens then BAM the 3rd just sits there then times out. Went up 2.5% then nothing and sure enough times out. The tune that I have someone else got it this close. it's a 2007 tb 4.2 with gt45 turbo 850 cc injectors. looking for some insight on how to get it to push threw this issue im having.
