Dyno results 100 shot with graph
Correct you will be pulling 6* of timing. Also one way to help do away with the lean spike would be to shorten the fuel hose up at least 4-6in. Also we like to see the AFR around 11.8
The Best V8 Stories One Small Block at Time
Honestly, I haven't heard one benefit of having a '98 LS1. Apparently the heads aren't as good (who cares) the rod bolts are weak, the PCM isn't as user friendly for tuning, and the oil passages on the '97-98 blocks aren't as efficient as later years. Plus it obviously doesn't come with a LS6 from the factory.
We run it around 13:0 A/F
But we check every plug every pass and have different jets in most holes, different timing in most holes and different fueling in most holes. Hell I dont think we have 2 Cyl.'s that are the same.

If the car has stock timing on most applications for a 100hp shot you might not have to pull any timing but on the other hand some cars you might have to pull up to 4*. It differs from vehicle to vehicle.
