Default How much extra timing for low comp Ls ***TUNERS CHIME IN!!!***

SO im trying to figure out how much I should advance my timing for my low compression. Here is the rundown, b18a1 stock hg, wiesco -12cc dish puts me at about 8.1/8.2 to 1. Now with the lower compression I know I need to advance my timing in turbo edit, but I have no idea how much to bump it. Im not running my turbo yet, im gona throw my 750cc injectors and tune the whole thing n/a and once thats done start street tuning with the turbo on.

With good gas and low compression, probably a lot more than you'll feel safe running.

Look at the timing in the OBD1 maps too.

LS will run good on donkey **** gas, crank the timing NA and then crank the boooooost.
