We could have made plenty of power, but not with your timing requirements. I thought stock power levels with over 2 degrees less timing than stock was pretty decent.
Your car sounds great, BTW.

MBWorld Fanatic!
Wayne, Have heard many good things about you in the little time you have been with LET. Could you please advise maybe thru PM or if you would like to disclose here, your tuning capabilities for the V12. I am considering going Nov 1st.

Our V12 development was delayed slightly by the move, as we've been swamped with the 6- and 8-cylinder projects.
With that said, I would recommend you attend the event firsthand to see our results. I would prefer the forum members personally witness the before/after dynos themselves rather than a random sheet of potential vaporware.
Gains are in-line with other respected tuners, and sometimes a little bit more.
I have PMed you my number, if you have any further questions. Please let us know how we can help.

Wayne,
What's your take on adding a TB after an initial tune...
Current mods and or mods installed for a Nov 1st tune:
-ASP Pulley
-Thermostate
-K&N Filters
-X-pipe welded in
Afterwards, adding a TB... do you see it necessary to tweak the tune by adding a bit more fuel as the consensus of a TB install would be allowing a little more air intake and hence need a bit more fuel or is the ECU learning curve able to distinguish and eventually add a bit more fuel to cover the difference in air intake?

I believe the TB to be within the dynamic range of the ECU, given that your car will be dyno-tuned. With a less 'precise' tune on your car (eg: mail tune) it might not produce all of the power possible without a tweak. Don't get me wrong - there is plenty of power to be made with our mail-order tunes.
My LT fuel trims after a dyno tune were 1.5% correction or less after 3 months. There is no substitution for a custom tune on our finicky cars, IMO.

Dyno on my car to date is from the previous owner. ASP Pulley and thermostat and it put down 413/501. As you can see from the graph, lots left on the table due to fuel dump from the addition of the pulley with no tune. I would think 20 more to the wheels can be had just by leaning A/F back out to around 11.9 or so and me having installed K&N filters.
That said, I look forward to an LET tune on Nov 1st.
