Ready to give up
#1 · June 3, 2023, 7:00 am
engine swapped a 5.3/4L60 into a hot rod and went with the 500hp Ultimate LS system. Nothing but
problems. I will admit I am pretty new to efi with a very limited knowledge. I'm not going to go into
all of the details of what I have experienced and the lack of support I have gotten from the manufacturer,
I just want to find a good, reputable tuner who is familiar with the Fitech system and who is in close proximity to me in
SW lower Michigan to take it to and let them fix it.
Anyone out there?
