We have have two rigs, and a 3 bay garage, so I can put my truck in there when they are both in. And I wouldn't let them sit outside in the cold, I am the one that keeps the maintenance up on them. And I know the plenum is good because I went though my uncle who has as dealer license and they got it from the dealer only auction. The auction comes with a 6 day warranty, and in order to get that you have to let them inspect the engine and all working parts of the truck with machines. they even use stethoscope's to listen to the engine.

 

Unless they check it for that specific thing, they can use all the scopes they want. If it was tested this way fine http://dodgeram.info/tsb/2000/09-05-00.htm. But I would check it my self to be sure.

 

how the tune up go, any improvements on performance , i know when i did the 1st tune up at 120xxx there was a big improvement

 

Tune up went well, no real big improvement in performance. But there was really only one wire that was pretty bad, rest was just the carbon build up. But I'm sure my mpg will be better.

 

my gpa has an 01 and on the rad. support there is a handwritten sticker for pcm for spark knock....so i dont think all of them had DF from factory

 

No hand written stickers in my engine compartment. But this is my first time driving a Ram so I don't have any thing to compare it to. I will just have to save up a lot of money and buy the SCT programmer.
