So now that I got my heads and cam swapped out it's time to tune. Went and plugged in my predator to do a data log to send to 06 monte ss for a custom tune and it won't power up. Any ideas what could be wrong or how to fix it? It's a Predator for an 04/05 silverado. Kinda bumming because I can't even put my stock tune back in if needed. Thaks fo any help in advance

 

if your diablo wont power up when you plug it in to the obd2 port you probably have a blown cig light fuse, i cant remember if it underhood or in the ip on the drivers side but look for a blown cig fuse

 

thank you very much. exactly the culprit. And I found it under the hood.

 

no problem, i was hoping i could be of some help to someone on here
