Dyno in north texas and metro plex?
All the shops mentioned are still open. RPM can probably get you in and out quicker than HPP, most of the time I was in/out in 45 minutes. HPP is really busy and I would just leave me car there for them to do it whenever they had time.
Scott at A&S might, RPM doesn't do LTx and HPP only does OBD II. OBD I you could contact Jordon Musser. I'm not sure how his business is working out but he can tune it. Other than that I'm pretty sure it's mail order only.
