2000 454 VORTEC DUALLY TOWING ENHANCEMENTS
 

I'm getting about 9 mpg with an enclosed trailer....can it get any better with any known bolt on helps or is that about what is suppose to be ....any comments or hot tips on improvements ????

I installed a Flowmaster cat-back system on my 98 454 dually and it helped decreased my gas consumption by 1.5 mpg. It also seems to have more power as well. The stock monster muffler I have to believe is very restrictive.

I tried to fix your mileage problem on that thing, but no luck...J/K
Good luck...finding mileage on these big trucks is tough at best...

Hi

Use a throttle body spacer Poweraide, See if K&N have the Fipkit for your model and use a Superchip power programmer, we do a lot of these at our shop, they do help, if you can`t get the K & N try AFE, stage 2 if they make one for your model, you will have a little modifying to do to the Air cleaner/ Intake tube once you use a throttle body spacer but it is worth it.

Hope this helps
