Ok first-- I have a 2000 4X4 Tacoma 3.4 S/C 5 spd with URD. I have a 2 1/2 in lift with 32's, dual exhaust, 41500 miles, deckplate mod, and live in AK. My fuel economy is getting worse by the day. It started after installing the URD kit this last summer. I almost NEVER go into boost, I have a very light foot, never go abover 3000 rpms, I use only Chevron gas, I replaced the fuel filter, never had a check engine light, and cleaned the MAF---this last tank I got 184 miles to an almost empty tank----frikin horrible--mine as well drive a damn hummer. Can anyone think of whats going on? I have not tuned the vehicle yet---hopefully soon. I am running the settings gadget sent with the R4 software. I dont have any ping but maybe its running a little rich? Thanks for any help---Dave
PS Can anyone send me a copy of the R4 software disk or post it for a download--I lost mine and I got a new computer after my last one fried. I would pay to ship it up here.
