I've had good success running their low pressure tune ups, but Steve is right. They are usually on the fat side and I end up pulling fuel. I've never tried their high pressure tuneups.

What's the compression and what fuel? What did you find in the engine?

10psi flowing would usually indicate 10psi through the appropriately sized jet, or through a 73. Depending only whatever school of thought you believe in.

I pull 4 degrees on 100, 5-6 on everything higher than that. Same plate. 418 sbf 11.4 compression with 114 fuel.
