Hell yeah! in what part of the US, assuming you're American, do you live? I searched thornbury and I think it showed up in Scotland. definitely somewhere in the UK.
My machine weighs over 6000lbs with me in the driver seat. I'm also running 35's on steelies with 4.88 gears. those are probably the specs that matter most aside from mine having actually full stainless headers due to it being a non-VVT-i V8.
We could certainly share and study one anothers maps and possibly learn from them. I wouldn't want you to use my map for fear of damaging something. It's your life though.
Also, don't buy the O2 sensor cat from [MENTION=122163]duffdog[/MENTION].
The widebands will tell you if you have any exhaust leaks.
