View Full Version : timing ???

03-25-2008, 12:27 AM
I'm currently running 26 degrees with mods in sig and a 100 shot. Plugs look good and had it checked with hp tuners or efi live (one of those) and there was no knock. I'm thinking od going ahead with the 150 much more timing should I ull for the 150? Would 2 more degrees be sufficient or should I pull three to be safer?

I think to be safe you should have a wideband or have it on the dyno to watch the A/F Ratio..... My car is running out of fuel press. on the 100 shot after the cam and bolt-ons......

I have a fuel pump and wideband with the lean shutdown switch

3 would be safe. personally I would pull 4. It is better to be slow than to get a tow home.
