This may be entirely irrelevant, but throwing it out there. I did it with mine because the dealer had 87 in it and the car felt like a slug.

what is the stock timing in high and low tables?
I can do a data log to confirm what timing is before pulling any fuses. and if it is low timing, then i would pull fuse, and log afterwards to confirm.
on my 4th gen f-body ls1, high tables were about 26 degrees and low was 20.
edit: see attached log from last night. Just messing around and first time i logged my car. 8.5 psi of boost, 84% TPS, and 22 degrees timing. Normal timing?
