Default 5.7 V8 Hemi Engine

Was reading about the 2009 Ram1500 on Dodges web site and the 5.7 Hemi will get a boost in horsepower to 390. The V6's and smaller V8's horsepower showed no increase but I will have to check that again to make sure.

You are right about the Ram getting a power boost. Correct me if I'm wrong but all the vehicles that use the 5.7L Hemi are getting a power boost. Pretty soon they are going to be pushing out 400HP. I call that a amazing to get 20MPG and 400HP.

My current truck won't break 20MPG and only gets 310HP.

I think I read somewhere that the power boost is the result of variable valve technology, or something to that effect.... I've had to look again to be sure.....

Welcome to the forum! Most people are using the Superchips 3815 programmer along with a cold air intake and aftermarket exhaust.

If it's the same engine as in the LX bodied cars, I would highly recommand the Diablosport Predator. You'll get the best bang for the buck.
