there shouldnt be any fluid coming from the pcm... really have no idea what that could be outside tranny fluid.. but again i would have no clue as to how tranny fluid would get up to that part of the engine bay... as far as the piping coming off before the maf... it should be alright because there should be a screen on the maf sensor piping.. that would stop major things for a short amount of time.. but definitly should be fixed asap... and as for the wizair piping... best bet is pvc... it sucks cause i used 3 inch piping because the stock maf is 3 inch and i didnt want to try and mess with the maf too much in fear of breaking it...its a 22.5 degree bend off the tb straight back to the wizairbox... i like the pvc because its staright smooth tubing unlike the air duct wizair comes with that looks like the duct from a dryer... good luck with everything i hope i was of some help
