This shows gains across the board. I love my mods and there's no harp on torque at any point in my rpm range. I can get my jeep sideways from a stop. (Trying to whip it of course, it's no drag car )

Even without tuning, the ported manifold I did showed the best gains from 2.5k-5k. The owner reported zero drivability issues, and his low end was just fine. Whatever low end that could have been lost could have easily been regained with tuning.

Re: 210 to 300 hp? 230 to 330 ib-ft?

Swap the 3.7 Powertech for the new pentastar 3.6l that puts out 285hp. I dout anyone has done this yet but the transmissions used are the same for both engines--(W5A580). just throwing out a suggestion.

Re: 210 to 300 hp? 230 to 330 ib-ft?

Hm..... Good to know.

As much as I live my jeep and engine, I've heard the 3.7's are known to eat itself around 140K.... Let's hope not tho.
