Power loss
I went from 285's to the H2 wheels and 315 BFG's. About the same time I put my 1000# custom camper shell on. It seems to bog down a bit and I have to stomp on the padal to kick it down and go up grades now. I have 3:55 gears. I have a clean fuel filter, new BHAF,fixed the exhaust manifold with an ATS, and cleaned the IAT sensor. I have no performance mods (check my sig below to see what I'm driving)
Would the tire size and camper weight effect my performance like this with the 3:55 gears? I am stumped and need my power back. Any advice?........
ps.....for those who will most likely ask........I will install a fuel pressure guage after I am done moving next week.

Also..... cruising down the freeway at 65-70 I am at 1500 rpm. The motor sounds like it is bogging a bit. I still have not gotten my speedo callibration taken care of yet. Would that help since the shift points are supposed to be callibrated too ?

TD,
Maybe time to start looking into fuelling. (injectors and a "box").
The Edge EZ is a mild tweak but noticable when things get locked in and wound up.
I understand injectors get at things a little lower to help the wind up but that would require a beefed up TC and VB for an auto.
Lots of info here, do a search.
Oh, gauges are a must buddy. Especially if you start to mess with the fuelling. (noticed none mentioned in your sig)

Plug in your tire size numbers here:
http://www.1010tires.com/tiresizecalculator.asp
It will tell you how much difference there is between the sizes.
You'll either need to change gearing, or up the HP/TQ to pull those larger tires & the extra weight.
Getting the Computer/speedo corrected will help with the shift points.
