New flash,is my truck derated ?

I have had the new flashnow for about three weeks. The other night I had a little stop light action with a Chevy 1/2 ton ,out of the hole I pulled him by 4 trucks and then my truck shifted into third.The acceleration flattend out nad the Chevy started to reel me in, had let out of it due to traffic.This is the first time I have realy gotten on the truck hard with the new flash.I was told it's the latest flash and it deals with the turbo and driveability issues. Before this new flash I would have smoked this gas truck, my truck pulled as hard in third as it did in secondand would bark the tires going into third, now it just shifts very smooth with no hint of wide open throttle. My truck does not have the power that it did before, the new flash seems to deal with the soot by defueling the truck. Also it started bucking during a slow speed shift the other night . I have to wonder if it is related to the new flash.

i love the way these new trucks look! But man it seems like the computer is the worse thing in the world for it and every time you guys add something theres always a problem. I wish i could get a brand new one without the engine or trans and do my own thing with it!!! That would be great.

Most of the bucking issues I see on the 6.7 are turbo issues..........

I think all these flashes would drive me nuts. I have a friend who totaled his 05 and he wants a new truck, but he doesn't want a 6.7 with all of it's issues. Are most of you happy with your 6.7's?

Happier than can be, once you get rid of a few things, Got my 08 in March and have never had to have it flashed.

The joys of owning a 6.7! Does not matter if you have an 07 or an 08 these problems will continue!

Are there different flashes for the CC vs the pickup? I do have the AV flash got it last week should I have got the AY or AZ? Should we only get flashes if there is a problem with our trucks or just because it's available.

Yes the C&C flashes are different than the truck ones.
