I have a new build  557 Ford, in a new built 1956 F100. My first 56 died a terrible death, ethanol related. To Avoid a repeat, I decided to go with the FiTech go 1200. I may be over my head with this computer tuning thing. I hope you all can be patient with what may seem like stupid question. I will get what ever info I need for you, just let me know.

Engine is very hard starting cold, not bad warm. It backfires through TB unless you add throttle.

I have taken prime shot to + 100 and doesn't seem to be changing anything yet. It has awesome throttle response once warmed up though.
