i am not a tuner for the most part just a normal mechanic.
i have been using hp tuners to change tire size gear ratios trans tuning code and vats deleat on swaped vehicles.
i have a 2009 silverado 1500 4.8l has tsp stage 3 low lift cam and long tube headers installed.
i had the truck tuned by a dyno shop that came highly recommended.
the truck runs real good given its only a 4.8 on 35 inch tires but it smells real rich at idle like makes eyes water rich.
i was have been watching data and fuel trims are real high at idle and part throttle im not sure if this is normal after tuning i have checked for vacuum leaks and cleaned the maf. also i cant seem to get vcm scanner to do the idle learn
i bought an afr setup to get more info and make a log file for anyone who is willing to look at it.
any help would be appriciated.
the log file posted is without the long term fuel trims turned on that is how i got it back from the dyno shop i have since figured out how to turn them on but need to record a log file to post.
