I Have a Complete 4.6 and 4r70w from a stole rec. i bought for $450. Car was stolen of new car lot. Picked it up when i was a tech. at a ford dealer. It was trully a great deal. The trans I know about the soliniod resistance so thats not my question. What problems will I have if I use the stock Fuel pump and no chip. I have headers but wont the increased airflow cause a rough idle. What type of tuning software or chip would be appl.

Im looking for HPtuner type software not some chip somebody else says will work that i need to pay for reburns... babbies are calling cant type no more. any help greatly appreaciated. Thanks.
