| Diablo Sport question
Newbie here. Just changed the pgm on my fathers 04.5 lly 6.6 duramax to the 65HP 110LB's of thrust with the diablo sport predator and noticed it shifting somewhat different. Anybody have this observation? Also, he is going to pull his 11klb rv occasionally, and I noticed the instruction said you should limit towing to 8K with that setting. He told me about the RV after we uploaded the program. One other thing, at what point do we really need to consider changing exhaust? My father wanted some more efficiency with his factory duramax and after talking to others, we decided on the diablo sport.
Thanks in advance. |
