Please, does anyone have any input on this at all!!!!


Thanks in advance for anticipated response!!

grasshopper, are you sure a TSB was issued by GM on this? I went to the TSB section here on this forum and found nothing on an overboost reflash TSB. DinoMaxhttp://www.dieselplace.com/forum/smileys/Big Smile.gif http://www.dieselplace.com/forum/smileys/Big Smile.gif

Yeah there was, for early model 01 trucks. Pretty sure later models it wasn't an issue. Don't have the number. If you have an early model 01 that hasn't been reflashed call John Kennedy, I'd bet he knows

Kennedy, do you have a number for me, cause if you do that would be nice to have when i send the guy to the dealer!!!!!!http://www.dieselplace.com/forum/smileys/Big Smile.gif

I just looked in ALLDATA and on GM's website, I cannot find it either. I looked for an 01 and an 02.

My truck was reflashed last October and I still get an overboost code quite often, usually when running stock.

Whats your VIN?

New TSB coming pertaining to "aftermarket air filters" due to be released any day now so be sure the box is oil free...

I read the info on the above link, what programming has to be done and why, after modifying the box?http://www.dieselplace.com/forum/smileys/Confused.gif

My take is that it was to update the relationship between MAF and boost due to velocity and flow changes, and possibly to widen the operating parameters...
