Just reading this now... Also lookig into CarSoft, but probably buying the new (legal) version 7.3 direct from CarSoft for ~$500.00 as it is worth it to me... Anyway, going back to the fuel pump off, I suggest you check this. ti's are famous for having failed fuel pumps, and in fact mine was replced twice under warranty (1998 model year). Might be worth a shot, as a drop in fuel pressure might take a second for the DME to recognize and correct thrugh opening the injectors more, causing the surge. Just thinking out loud for you... |
