NA: 342/275. Anyone higher?

Jordo!

I haven't followed every post here, but I it seems as though there is still debate over the value of having access to the VVEL maps.

Here's a simple way to determine their value empirically.

Re-load the previous tune where fuel and timing was optimized for Mike's set-up using stock VVEL mapping. Fine tune as needed -- leave VVEL alone. dyno three runs. Take the best.

Then load the tune with optimized fuel, spark , and VVEL tuning. Fine tune as needed on all relevant maps. Take three dyno runs and report the best.

Compare and contrast -- question answered.

If Mike makes another 10-12 whp (or more) at points throughout the rev range when adjusting all three parameters together as opposed to just two, clearly having access to the VVEL maps is helpful for extracting maximum power.
