I've was having nasty startup and idle romps including while at stoplights. Decided it was time to do something about it. Dealer tried the first time and failed. The second time they flashed it against my orders not to. I do NOT have any of the problems that i experienced prior to the flash, but I've lost about 1 mile in fuel economy and some hp. I don't work the truck hard in terms of towing and heavy loads, so the final result is better than what is WAS doing. But I'd be unhappy of I relied on the original hp.
I have 190k on the truck now and have been very satified overall.
