I think I found out why my car was weak in the 4000-5000 range, turns out that I had a different distributor than my stock 82 one and it was adding 36* of advance (18L advance slot) to go with my 16* of initial, giving me 52* total! No wonder I always had to run 94 octane gas! I can't believe that it still ran as well as it did!.
Anyways, thanks guys, live and learn.
