ECM re-flashing and fueling box question

[**ICEMAN**]

will it hurt to have my powermax or ez connected during a ECM reflash?

my dealer dont have a problem with my aftermarket accessories so if i dont need to unhook it for a reflash i wont. just concerned about damaging my boxes.

TSB 18-24-99 for intermittant stumble is what i wanted to try while it was there for a few other minor things before the 3/36 runs out. any one have any luck with the reflash. i might not stumble for a month or longer or it might do it twice in one day.

seems alot less since the inj. install

ICEMAN, I had that reflash done on mine about two years ago, have not had a stumple since.

I don't know the answer about leaving box on, if it were me I think I would disconnect it first.

My comp was left on during a reflash,it didnt bother it,from what i can tell.

I don't know if keeping the boxes connected will hurt but the reflash works. Had my truck reflashed in March of 01 and havn't had a stumble since.

I had my 99, 2500 reflashed last year at the Dodge dealer in Kenai, Alaska. The bad news is that I lost 2 miles per gallon. The good news is that it cured my stumble. They also charged $35. 00 per flash. I went from 20 mpg for all around drving to 18 mpg.
