Answer to: EGR Valve intermittently sticking, what would you do?There is an Electronic control module called X-TREME POWER that gets rid of of this and other EGR common problems. I found it at www.egrxtremepower.com and It has done wonders for my truck and my pocket. You can install it yourself (I did), and you don't have to delete or change anything on your engine. You don't need to spend a dime on mechanics or reprogramming your ECM. Just take a look at it and see if it suits you.
Answer to: Anybody use an EGR Tuner?The EGR system is built in your engine if it was manufactured after 2002. It was designed to lower NOx emssions but I created a lot of problems; Coughing, black smoke, power derate and surges, and a lot more. What all these devices try to do in different ways is to get rid of all those problems. I tried the one in www.egrxtremepower and it does great, no mechanical problems, more power and better fuel mileage.
