Since it's surging and not shifting properly I say take out the tuner, and cleaning the egr vavle is always a temporary fix, it always seems to need to be cleaned again every 3 to 4 weeks it goes bad again, and you need to electronically check the the injectors, and change the fuel filters, go with cheap things first and progressively get more if it doesn't fix it, need to check the boots too, and a thing I would do is check for blow by, check ur crank case vent for excessive flow and open the oil fill and see if u got a lot of vapor coming out of it... If there is a lot you probably have a bad seal, or cracked piston, blue smoke isn't good, but could be because of the egr, white means it doesn't have enough heat to burn the fuel, white is okay as long as it isn't going it when it's warm, black is fine as long as it's not at idle if it is then it's most likely a bad injector.
