Running west up the pass on I-90 this wkend came across a Duramax towing a small 14ft aluminum boat. I had 4 kayaks up on the lumber rack (fair amount of wind resistance) and the bed loaded with camping gear. I kept trying to put the pass on and could not get around the D-max. It was all i could do to maintain 65-70mph on the steeper grades. Been wondering if i might have some tired leaky injectors for a while now as the truck seems to be a little down on power. Not a good feeling when your neck to neck with a chevy and can't pull ahead. Guess its finally time to have Don check out my injectors and get the smarty jr ordered. Anyone know if Isspro is still doing the rebate on the performax gauges??

 

Yes, they can be fast and yes, you are stock.

 

The winch, big bumpers and bed cad is extra weight also.

 

How many miles on the truck? @ 145K my injectors were toast, got new ones and added a few things as per sig. and can now pull the I90 Snoqualitypass going 75 mph with a 10K trailer and still have power to pull past a Dmax. If you got the mula you can have mo' powa.
