I ran a 24lb injector calibrated 77 pro m maf for about 7 or 8 years in my SHO, using an optimizer. I worked great until the Optimzer took a crap.
Now I am back to the original set up, and I feel a hp loss at higher rpm I have not been able to find anybody selling the Optimizer any more.
I tuned the idle by trial and error, and I kept the mixture a bit rich all the way to redline.
I miss it now.
