I'm new to all this fuel injection stuff. I just bought a 1990 GT with a 1999 Explorer 5.0 that has not been final assembled. The previous motor that ran in the car was a highly modified TFS top end with a big MAS air meter (not sure how big, but much larger than stock and full length headers. I intend to leave the Explorer motor stock with a Mustang upper and lower intake with a cold air intake and shorty BBK headers. I do not have access to the owner that modified the car. Can I use the computer in the car or do I need to replace it? If I replace it does anyone have any advice as to which would be best? I intend to use this car to commute 75 miles a day to and from work, so I would like to keep reasonable mileage and the most dependability I can get.

Thanks so much for the info, I just pulled the chip. Does anything go back where it came from? Is that chip sellable?
I have the Explorer intake, should I try to make that work instead? Can I use stock Mustang air meter and parts to straighten out that 90 degree elbow? I apologize for my ignorance of the parts, I'm an OLD carb guy, this is my first fuelie motor.
The explorer intake can be adapted pretty easily, its a very common mod. The biggest thing with the explorer engines is they are truck engines; built for low end torque more than anything else. The cams are not the same as a mustang ho motor. There are tons of write ups on this an other forums about explorer parts and engines. Search gt40 intakes to start.
Thank you very much for your assistance, I believe I have a plan. I'm using the Explorer intake with a Mustang EGR, MAF, TB, and cold air. I like low end torque so I'll stay with the Explorer cam for now. I may be back with more questions after I light it off and it runs goofy!!
