ficm flash and maybe ecm/tcm
I have a few questions that maybe someone on here could give me some insight on. I have on order the programmer to flash my swamps 58v ficm. I have talked to php but I still would like some more info. I have a 2004 with vxbc9n8. I have a sct with innovative extreme street and gearhead srl+. I am wondering if changing my strategy back to the recommended vxbc4 and having new tunes made for the vxbc4 would be worth it. Will I see an improvement in mpg? Do I have a good chance of needing a new ebp sensor? If I will see gains in any way then I want to go for it but I have heard that with the sct tuning it might not be worth it. If anyone has some info please let me know. And thanks for taking the time to help.
