Shorties do not improve power on these engines.
Gears are a very noticeable gain also
If it were me.. my move would be to save for a full exhaust system (LT's, high flows, x pipe and maggies) and start with E fans. Once the exhaust goes on, a tuner would be next. r

 

Then you're going to have to get a game plan together to explain why $4K in mods to improve fuel milege has netted you a $500 loss per yearly average in fuel!

Yes, I said loss because all these mods have made your truck so much fun to drive you'll be running the snot out of it, LOL!

 

Well only paid 4k for the truck! Haha good to know thanx guys

 

I lost that just changing out mufflers

 

what mpg are you getting know

 

Im getting around 12 mpg

 

If your heavy footed, that is probably about right. Maybe more toward 14 would be normal.

 

nope thats driving with my daughter in the truck! and not road raging! haha it did have a misfire on #4 when i first got it and had it for sometime before, maybe the cats are plugged up?

 

If you think the cats are plugged, you can get them tested at a muffler shop.
