Staying with the drive by wire and production style pcm creates another potential issue not brought up yet....what trans are you going to use? If the trans requires throttle pressure/kickdown input from the throttle, then check out the Bouchillon setup/'03 DR based pedal assembly (it isn't on their website, call them up). The trans will be a 545rfe 5 speed auto from a 94 ram, which I know sets off a string of other issues. Street and performance did give my harness a hair cut BEFORE I bought the set up, so I am not sure of all of the perticulars there. [That box is still high on the shelf.] I now have two computers, not sure if the second one is an after market from S&P or if it is for the trany, but I havn't got to that stage of concern yet. I have heard that certain tranys have there own seporate computers. Lots of good feed back from everyone,
