Default tips on tuning NEEDED! 94 lt1

ok im sorta new sorta not i signed up a year ago and never on here but i hated the last forums i was on so im trying this place!

the culprit! a 1994 camaro z28 m6 lt1

i need advice on tuning it

it has ported and polshed heads and intake heads flow 285 cfms at .550 lift

headers, gutted cat, and hooker crossflow

11:1 compression ratio

7-503-08 comp cams
with 503/510 lift 224/230 dur @.05 112lsa with a 4 degrees advance built in.

26lb accel injectors (actual flow is 25.7)

3.42 gears and i even sent away for a mail order tune to pcmforless and still felt like it was holding back im streettuning it and its getting better

but was wondering if anyone else has tried tuning them selves and know what total timing i should have and what numbers the volumetric effiency should be set at thanks...

You really should get a wideband O2 sensor that way you know exactly where you are at as far as fuel. what tuning program are you using?
