Hi!
Can anyone tell me if 17 is a reasonable spark advance at 6000 rpm and 250 lb-ft on my engine?
The engine is a LS1 with 243 heads, LS6 cam, Holley Single-Plane Intake Manifold 300-163, Holley Four Barrel Throttle Body 112-587.
The dyno tells me I get less than 200 RWHP which is a disappointment.
I would really appreciate if someone could take a look at supplied logs and tune file.
Thank you!
