Need help on a base tune

:confused: Need help on a base tune
On my 92 GT I have a Novi 1000, Morpheus pipe, and a 3.00 pulley.

My Mods are

stock block
stock rods
forged pistons
10:1 compression
E-303 cam
Eldebrock Preformer Rpm heads
GT-40 upper&lower intake
1" Phenolic intake spacer
42 lbs injectors
70mm T-body
75mm Pro-M
MSD 6Al
BBK longtubes
3" exhaust all the way out
Adjustable FPR
stock EECU
Electric fan

I have the FP set at 42 LBS
I'm going to get colder pulgs, how many steps colder would you go and how much gap? what other things can I do before I go and have a dyno test and tune, I do all the work my self, I looking for somethings I can do myself, I'm running 38 degree's of TOTAL Timing, What do you guys think about my timing is it too high? The novi 1000 is making about 10+ lbs of boost. The car is mostly a weekend car I have good driveability now and want to keep it that way. Any help would be helpful.

Thanks,Rusty
