Re: checking if truck is running stock tune ?
Factory flash should take it back to stock.
I would maybe see if you can get hold of a tuner where you can "download" the "factory" tune from the pcm
. Which in your case, may likely be aftermarket. Then get in touch with a tuning company, have them look it over, and give their opinion if it's been tuned.
, there may be a fooler for the egr
