After yesterday i noticed that any type of load my truck falls on it's butt! Yesterday i pulled a riding lawnmower on a trailer and it felt lilke i was towing a bobcat, does anyone know what the problem could be?
Do you have boost gages? Low boost will cause that- leaky boot-? - Pull the driver's side boost tube and check the entire tube for holes-- some contact the power steering hose and wears a hole-- they will usually smoke a lot when that happens.
A dirty fuel filter will cause problems-- if in doubt, change that.
check the usual before i would start to worry ... fuel filter (stated it was new so check) air filter and check for leaks if it is not an air problem then next would be to look into fuel
correct me if i am wrong but doesnt the edge juice read boost lvls up to like 32? not fully familiar with them
also i would try to set your programer back to stock and see if maybe that might be a problem .. i have heard the the attitude is not the best tuner for our trucks and have heard of quite a few people running into problems with them
