turbo surge/flutter

this weekend i rebuilt my oil cooler, flushed colant, egr delete and new stc fitting in my truck. all went smooth and truck seems to be acting completely normal except for i seem to have some compressor surge now. performance mods are sct with srl tune, straight pipe and cold air intake. i have never had any surge until today when i got it all back together. on my turbo mustang i run a bov to get rid of it,how do you get rid of it on a 6.0? is it bad? i know on engines with a throttle body you dont want it because its hard on the turbo. could i have put something back together wrong, not sure why it would all he sudden start? any help would be gretly appreciated. thanks

When you did the EGR cooler delete, did you leave the EGR valve plugged in electrically?

No. Egr valve is out and wire is just there. Does this make a difference. Tune I have turns the egr off

I have the same problem after EGR delete also. Not noticeable on stock tune, but with a performance tune is loaded it flutters pretty bad.

Read posts #7 & 15, click the link on these posts. Unplugging the EGR valve might cause issues with other functions on the motor. If you still have the valve, it might be worth a shot to plug it back in and tie up to the side. Please report back if it made a difference.
SCT Tuner repace need for EGR delete?

You also might need a GOOD code reader to pull the hard codes (SCT not a good code reader). Or get a hold of a good scan tool to see what is happening when fluttering.

So if reading this right, if you have an 06/07 truck with new flashes from ford and and egr delete and block off plate, this may cause fan and boost problems? So I guess I can try bolting andplugging the egr valve back in to see if this fixes my issue. I tried pulling codes with the sct and I have none, nore do I have a light. This is just confuseing but ill give it a try. Will report back with findings

From my understanding, no one has figured out what year/stradegy is effected by the EGR valve being unplugged, so your better off just plugging it back in. Without a good scan tool, you'll never know it the fan is reaching full rpm.

The SCT isn't a good code reader. Some codes are won't throw a CEL. Not only are their "P" codes, but also U,B,C codes that alot of code readers won't read.

Unplugging the EGR valve may also limit your boost to 20 psi. I think it is a failsafe written into the PCM and isn't specific to a strategy since it can't seem to be overwritten with custom tuning.

egr valve is cleaned, back in and plugged up (is there a gasket or o-ring that goes between the valve and the intake? cant remember). so i took my drive to work this morning and the first time i got on it it sounded like it surged again. after driving a little longer i did it again and it seemed fine and continued to seem fine. im not sure if it feels down on power but it still blows the tires off, 37's.
one more question, if having the egr unplugged did throw a code but my sct did not read it or the cel did not come on do i still have to get it cleared or am i fine?
