Problem with surging
Ok, I have searched and searched for threads about the problems I am having and I have tried about everything that has been suggested but no luck fixing the problem.
I get a surging in my truck when it goes into overdrive (i.e the TC locks). It surges as soon as it locks up but seems to smooth out a bit once I get above 65. It is worst when it is between 45-65.
So far I have done a EGR delete and an SCT with the SLR tune from Matt, I just put a new torque converter in this weekend (this seemed to help a little but not completely). I have checked all drive shaft components as well.
I have tried putting the stock setting back into the ECU and the surging isn't as bad as it is with the SLR tune on it but the difference is very small.
At one time I had two Fault codes, P0113 and P0266, but the last time I check with my Edge Insight they weren't there. I didn't do anything to fix either of these either.
I am lost and am not sure where else to look, do I just bite the bullet and take it to the stealership?
It is a 2005 F250 crew cab Fx4 on 35's, it has a 4.5 exhaust with a cat delete pipe, Sinister EGR delete, SCT tuner with Matts SLR tune. IT has 103K and regular maintenance.
Any help would be greatly appreciated and sorry for the long post.

Not much, just a DD.
