edelbrock efi question

[jeeptech77]

im hoping that perhaps some one has had this problem i have a pro flo 3500 on a small block i know its not the greatest system. but at idle the iat defalts to 55degrees and when the throttle is slightly opened it goes to actual temp only when (running) i have ran this since 1998 and never been a issue till last year all the wiring resistance checks ok all grounds are ok tps replaced and set ecm swapped, cal module updated, iat swapped, ect swapped,hego swapped, i realize asking to diagnose a problem from the net is foolish so im just looking for off the wall awnsers..as well im considering going to a wide band o2 for increased mpgs any info would be appreciated.. im also seeking opinions on a new system im not too framiler with whats out there i would like something digital with a fuel trim and block learn but not oem evap system control would be awesome as well is there such a thing .my future plans include a twin turbo set up .thanks in advance jason
