Hesitation is gone. Turbos whistles more on let off. My hesitation was never really that bad though. Wonder if an aftermarket intake now would not make that noise many have talked about? I had the noise with my cold air roush intake..... I am putting in airaid on in 2 weeks. I will let everyone know then.

 

I just drove home after getting the 12-2-10 update, there is a difference in the feel, but I will need to do more driving before giving a review. Thanks for the TSB update info!

 

Thanks for posting info about this TSB, mine goes in Monday to get it done!

 

Ditto, I'm scheduled 1st thing Monday AM for the flash. My dealer knew about the issue, but hadn't seen the TSB yet. I was first caller on it. My symptoms are minor but I'm doing it anyway.

My symptoms are minor too but I figure why not. Gas mileage is averaging 15 mph in mixed hwy and city driving even though I'm taking it easy to see if I can improve it but not having any luck. Also sometimes I get a pause surge pause surge effect on hard acceleration when pulling out on the hwy, seems like the turbo can't make up it's mind to kick in or not and when it finally does kick in for good it chirps the tires at about 20-30 mph and gets up and goes! I pull out on a hwy to leave my street where the speed limit is 55. I need to be able to get up to speed pretty fast in the morning traffic going to the base I work at. If I accelerate a little bit easier it seems to smooth out.

 

I will have to have the dealer check mine out on my next oil change.

 

could very well be the traction control kicking in

 

Is this (2012-02-10) the same TSB or re-flash that the OP had done?

Has anyone had this completed in Houston Yet?
Thanks

 

Just had mine re flashed. I didn't have the shutter as bad as some of you guys did but the fuel mileage was in the can 14 average. Just got the flash and the truck run better and fuel mileage seems to be going in the up direction as well hopefully this works for others as well
