Wonder how well a 3.5 pcm would run a 4.0, I know the 3.2 will run a 3.5, and the turbo guys say the 3.5 pcm and injectors have a little extra fuel with a bigger pump but they are using rising rate regulators. I'm really not sure what the guy that was running the 318 or 360 was doing. Guess you could anyways do a carb but I despise carbs, I hate when guys yank out tbi and put a carb on, it's like you can't figure out what 5 sensors do? On the old K based turbo cars you can just socket the pcm, download a program on your computer, burn it on a new chip and pop it in, if it doesn't run right you have to burn another, but guys have pulled the code apart and you can adjust petty much anything, burn a chip and pop it in, of course this is OBDI. Idk if there is anything out there that you can plug into the OBDII port and just adjust from a laptop.
