I'm running a '84 GPZ turbo, a tweeked turbo and an intercooler... 'course, 
I haven't had it running for about 5 months!    Trying
to get all the pieces back together along with my other projects..


I do have a progressive fuel regulator, I guess I didn't realize that
it was a 1:1 regulator.. Makes a lot more sense now.  I will have to watch 
total available fuel volume.
