I drove my truck to new york on tuesday. It ran very well with plenty of power. Coming back yesterday and also today it seems that there isnt as much power as there was. I also notice less ( if any) turbo noise. Any suggestions?

Truck is 02' Crew cab with a little over 80,000 miles.

Check your fuel filter, air filter or maybe your Bullydog **** the bed.

Yeah i thought i might of got ahold of some bad fuel up north. Id been running the Power service treatment in every tank and this time i didnt. That is probably why. I'll get another fuel filter today and change it, i just changed it about 5000 miles ago. Also Bully dog Tuner is a programmer, not a chip so if that is the problem its the computer in the truck, but the truck runs fine, just seems to have lost power.
