I am getting about 21.5 or 22 llb. boost with a TA49 & the adjustable (many thanks, Steve Wood) rod turned in with about 3/4" left on the threaded rod. This is what I suspect is tuner style, as I have an RJC boost controller on it but the RJC boost controller does not respond to changes so I suspect I have a compressed spring in it and just haven't fixed it yet. I run 100 octane unleaded and show no timing retard whatsoever on the sm. Steve, I will forever be in your debt. Remember when this car wouldn't get out of it's own way. I had a friend throw a tune on it, dial it in at about 20-21, now I am running about 22 and it screams. No knock retard. none. What a great feeling. Only thing is, now I just wait all week for the weekends to get the car out for its ocasional cruise. Oops, sorry about getting off the thread track. My apologies. Happy Memorial Day, too, to everybody.
