Default terminator x tune setup

Finally got my setup driving .
5.3 rebuilt.
arp studs, cometic head gasket
brian tooley s2 turbo cam
rings opened to 21 24
bw s480 turbo, 1.25ar t4
1250cc inj
tx ecu


at the moment I am only running 6psi boost , taken from an intake source.
without dyno or track whats best way to set timing. I thought I was being on the safe side but then sometimes I read maybe not so much.

24* at WOT and then removing 0.8 per psi ( so at 6psi 19degrees)
also set my fuel for 12.2 at WOT then gets to about 11.3 at 6psi .

You’ll typically wanna be around 26-28* at WOT out of boost on most setups.

12.5-13 afr is usually where I’m at WOT out of boost. 11.5-12afr is where I aim for in boost.

6 psi isn’t a lot so you can play with it. Without a dyno or testing at that track, you won’t know what is the ideal afr/timing to make the best power.
