Could these be the reason why the truck would just stutter, not run

I hope this is the reason, checked all fuses, alot of connections, with no luck, the truck has been running really rich on the stock 4.8 tune with the new 6.0
You all think this is the reason why it didn't fire...???

IMO dont you think a 6.0 would run lean with a 4.8 tune?...smaller engine size!....but then again...the O2's would pick up the lean condition and throw alot of fuel at it...but...idk...it could be possible!

my truck was running 10.9 afr on the wideband with the 5.3 tune so you might need to get it tuned i thought it would be running lean too but it wasnt. my was acting crazy for a little while with the 5.3 tune but it wasnt acting like that it was just a dog its 100 % better now with the hp tuners and 28 degrees of timing the stock tune was at 17 degrees.
