Guys have been tunning there factory ECU's on Buick Grand nationals & turbo T-Types for even longer. Just need to know where to look.
The Holley one I use allows plenty of tuning capabilities. And it is easy to do.
Well now I have machined a head with a much larger intake port. It is taller and wider. A much better designed divider is installed and the engine was running fine Tom
Need pics of the mods,this post is worthless w/out pics IMO.
