Summit and jegs both sell the cobra computer/mass-air unit/24lb injector's and since i have a custom cam from ed-curtis in the mail. I need to convert over to mass air before the new set-up goes in. I have a few questions my vortech will be here wed of this week and it said that it was for 86-93 mustang 5.0's if i did this conversion would it matter? i told ed curtis 30lb injectors for my set up so should i stick to that(will it change the cam all around)? i just didnt want to pay 500 dollars for a mass air conversion and have to turn around and get the thing re-calibrated for 30lb'ers
