Advice on hemi bottom end power
Hey guys, have a 2008 1500 hemi and am unsatisfied with bottom end power and torque. Installed a air-raid intake and can now really hear this thing lugging. Pulling a holiday trailer is painful, lug down and down til downshift, race up to up shift, start again. Will a tuner/programmer make much difference? Which is recommended? Can I delete MDS? Any and all advice appreciated. Upgrades are cheaper than trading, but am not too pleased with this truck.

I'm sure if Hammer reads this he'll give you the long speech about it but in simple terms the 5.7L Hemi was never designed to be a purpose built truck engine. As you know the 5.7 is used in a number of dodge vehicles such as cars. So the Hemi makes its power in the mid to high RPM range. That being said I don't personally think the 5.7 lacks on the bottom end but then it's the only engine I've ever owned so I can't really compare it. As for mods a tuner will help as will shorty headers.

I felt the exact same way with my 2500 with stock 3.73 gears and 285/70 17 highway tires.
added Superchips programmer, 4.56 gears, and even went to a bigger, heavier tire (Toyo MT 285/75 17) and it is a whole new truck. The superchips really pays off with how much better the tranny works, and adds some tourque/power as well, but the gears made a huge difference.

Nascar uses long tube headers ..... for the Top end power that they are looking for.
