Loss of Power
 
2 Attachment(s)
(Newbie ? here)

I have a 2008 4x2 5.7 hemi with a Procomp 6" lift on Toyo Open Country AT II (35x12.50x20). It feels like I have lost some of the get up and go that it had prior to the lift. Am I imagining this or is this a usual occurrence when trucks get lifted? Is there a way to restore the quickness I think I have lost by changing gear ratios, exhaust, adding a Bully Dog system?

Thanks

Jamie

If you went w the bigger tires at the same time, that's part of it. Larger diameter contributes to a greater moment of inertia, heavier tire too. Another part of it is that the truck is higher and is blocking more air. They already had the aerodynamics of a slanted brick. But now you've leveled and lifted that brick six inches higher. And something else. Your suspension components are now longer and that creates a greater moment of inertia due to greater flex.
Re-gearing it is the best way to get that performance back. A tuner is a cheaper way of changing the shift points..

i finally bought a new gear and went with the motive 4.56 and also picked up a 180 degree thermostat. I won't be home until mid march, but my parts will be there... lol

go for a superchips tuner...I did that with intake and exhaust and it has a lot more get up now after lifting and 35's, but gearing would be the best option i would think

youre gunna loose your power because of the tire weight my friend. get yourself a chip to bandaid the problem (which i did) or spoon out the cash for some gears and it will be a whole new beast
