Hey all, I am tuning my v3 microsquirt 97 explorer block, f cam, yellow top stock injectors, fuel pump 300lph, running TFI disty. Fires up idles smooth about 1k any lower it hunts a little. I have auto tune setup and let it tune a bit however my issue is.. The tfi requires 2 power wires. One in Run position another just for cranking. I have a power wire on a switch I use during cranking then turn it off. Then engine runs well with it getting power. Breaks up and misfires when trying to rev with it off.. maybe my main power wire Is weak?
Thanks
