His numbers seem similar to mine, I pulled 383 whp with API Intake, Headers, no cats, X-pipe, Borla, and Henderson chip. Ambient temp was about 50F during the dyno. I am not the original owner so I don't know if anything else was done prior to my ownership.

Mine is a '91 also. Will be porting plenum and injector housings and port matching heads next. Then re-tune again. Should give me about the same improvement I saw with the headers and tune first go around. Will have my new business set up by second week in September, so will get base curve on our Dyno before swapping to ported top end and re-tuning.
