[QUOTE="swampratt, post: 3310813, member: 15054"] My first Fuel injected car was a 1976 280Z and you could time the distributor the old fashioned way. If you went to the library you could find a lot of information on the FI system and how to tweak it. I was 18 at that time and found I could open the air flow meter side cover and have a few screws to turn inside that would change injector dwell time. Inside the computer there was also some more of that going on. That made it pretty simple to tweak things. Later I stuck a Cartec intake on it and mounted a 4 barrel carb. Power was up everywhere and MPG did not get hurt. FI is good in my mind if you plan on boosting the engine that way you have a lot of control over fuel and timing curves. You can get there with a carb on boost but I feel much will be left on the table. I like carbs and have messed with LS engines with carbs and to me they run very well ..instant throttle. MoBoost is a member here is a tuner and has a speed shop in MWC Abel racing. But he has quit the internet forum thing and concentrating all his efforts on his speed shop and his wife and child. Some tuners you must wait like 15 minutes for it to update then see if it was a step in the right direction or the wrong one. I know MoBoost Andrei said he hates those and will not mess with them as it takes 2 days to do what a good program will be able to do in a couple hours. Research that when looking for programs [/QUOTE]
