Gotta C5 with PRC heads, Torquer V2 cam and Fast 92. I've had it dyno tuned and it makes good power. Also runs good at the track. I just finished street tuning my G8 with good results. So now I've turned my attention to getting a bit more outta the vette. I took a log last night and noticed my WOT timing is about 20 degrees throughout. I've looked at other tunes and that seems pretty weak to me. Just wondering what you gen 3 guys are at for timing? I used to delivered engine torque on my G8 to tune timing. So I logged it last night on the vette with a HP math and seems pretty accurate to what my trap speed indicates. I got 92 octane where I fill up. Just wondering where some of you are at with a basic HCI set up. Thanks.
