I had no prior experience with efi. With a little help from delta t at pro-touring.com (he has a 383 with a vortech and holley efi) we got it tuned. Its not a hard system and does what I need it to do. Alot of people are running this efi setup with no problems. Sorry it didnt work out for you frank. I think its a great system for the $$. Chevytalk.com has a lot of info for holley efi check it out. A member on this site is a engineer for holley. I know alot of people are running carbs with no problems but for all the money you need to spend on a carb, wideband etc.. You could go efi for a few bucks more and tune on a laptop. Better than changing jets and airbleeds.
