more power

I have seen a few thread before about increasing horsepower, but I thought I throw it out and see if there is anything new out there. I recently pulled my ~4,000lb camper from MI to Washington DC. I was really disappointed with the power in the hills and the plummet in gas mileage. I got 8.4 MPG in the hills of PA. The truck is a 2010 DC 4x4 with 14,000 miles on it. I tow in 4th gear due to no towing feature.
Any thoughts on increasing HP? Improving MPG while towing?

 

Not really man, I think your best bet at real HP is gonna be a supercharger. Good luck though, I recently ran across the same problem towing my boat and now gotta upgrade to a Tundra.

 

There's no replacement for displacement. Supercharger will help, but 8cyl is better.

 

if your pulling something large you either need the towing options like trans cooler etc.. or you might need to upgrade to the larger tundra.

 

How much weight were you pulling? Also x2... tow package with transmission cooler or no? Towing high loads without it is very bad for the transmission without a temp cooler...

I towed about 3500+/- lbs with my prerunner (trd off-road with TSB AAL) over Grants pass (6% grade, steepest and highest interstate pass in the u.s.) and was blowing by people doing about 75 without even breaking a sweat. Also pulled about 11.5-12mpg's that run. In lower cali on 95 I was pulling 16mpg from Sacramento to Bakersfield...

It all depends what you're towing, if you're staying in the vehicles optimal raiting or not.


As for more power... boosted or bust. You can gain minimal power with some basics like DT Long tube headers, exhaust, high flow filter (only talking maybe 10-15hp's on the dyno here). Boosted is all you're gunna get for real numbers though (supercharged, turbo... whatever floats your boat).
