OK after reading on this forum and watching for sometime I believe I will give myself a try at some basic tuning, first thing I would like to do is my idle. would I be better off using the ostrich or burning a memcal I data log with aldldroid and would like to use that to tune with. burning would be more affordable for me but changing on the fly I think might work better for idle adjustments. I have a 7727 ecm on a 90 TPI corvette.
