Been reading through some posts on EGR,SERG, and different tunes. I have GDE full torque eco tune! I have unplugged the MAF but do not have a cell ! When i first unplugged the MAF i got the cell but it is no longer on is that a problem.I did the EHM which i run into the air box with a homemade oil catch can It still puts out alot of smoke even at idle smoke out of the tail pipe is not as bad after GDE tune except if i step into the throttle which is ok but overall im not that impressed with the GDE tune as far as mileage gain and power gain it felt like it pulled harder at full throttle before i got the tune. EGR still gets oil covered i clean about every 2K miles
