I have a 2002 GMC Sierra 2500HD Duramax and also have a BD diesel (on level 3) intimitador programmer but i find the truck a little powerless compared to other duramax trucks both chipped and stock.

The truck idles and runs smooth but can be a little hard to start when its really cold outside.

Please let me know if you have any ideas.

Thanks.
