I have tried all day to find this info so if there is a concise post existing please excuse me and post that link. I need more fuel for my 383 and did an injector swap on my holly 670 cfm tbi. I went form the holly set up injectors which were 61lb'ers to 80 lb 454 injectors. I just had the truck tuned and thats how I fond it was running short of fuel(and I have the dyno charts to prove it) I would like to try and just update the tune to note my new injector sizes so I don't have to pay for another one so soon. I cant seem to find what I need to change or where I need to change it, I thought I found a post suggesting to multiply several tables by .71% this lead to the truck running poorly and a check light. If I run the tune as is, it runs increadabl rich as would be expected. Thank you in advance.
