I got my tunes done today at Performance Dyno in Concord NH. Pete Johnson did the tuning. 
All motor. HP 302.59 TQ 317.54
75 shot HP 353.9 TQ 369.56
Remember this car has an automatic tranny. The HP #'s are 10-15 lower than a stick car with the same mods. I also did the dyno runs with the street tires so I can add about 3-5 HP to these #'s with the Bogart's and ET Streets.
I think the biggest difference will be that the torque management is now gone.

I put in a new set of stock HT1,s Still waiting for the HT0's to arrive. Went conservative on the timing.
AFAIK Bogart will only custom make the 05 wheels, They don't shelve them.

Your naturally aspirated A/F ratio is about 13.5:1, if I read the dyno chart right. I've been told many times that anything above 13:1 at WOT is dangerously lean. May want to take another look at that one.

Here's a little blurb which demonstrates that ideal A/F is dependant upon many variables . . .
"The Stoichiometric Fuel/Air Mixture
An "ideal" fuel/air mixture in which both the fuel and the oxygen in the air are completely consumed is called the "stoichiometric" mixture. The stoichiometric mixture is usually specified as the ratio of the mass of air to the mass of a particular fuel. For example, if a fuel required 10 kg of air to precisely burn 1 kg of the fuel (that is, all the fuel burned and there was no oxygen left in the air afterwards) then the stoichiometric ratio for that fuel would be 10 : 1.
Chevron gives the stoichiometric ratio of air mass to fuel mass for gasoline as 14.7 : 1, but doesn't specify the composition of this hypothetical gasoline.
From http://www.faqs.org/faqs/autos/gasoline-faq/part2/ comes the following table of typical stoichiometric air-fuel ratios:
Fuel Stoichiometric air-fuel ratio
methanol
6.4
ethanol
9.0
MTBE
11.7
ETBE, TAME
12.1
gasoline (without oxygenates)
14.6
An oxygenated gasoline with 89% gasoline and 11% MTBE would then have a stoichiometric ratio of 14.281."

Congrats on the new numbers! Can you expand on the torque management being "disabled"? Is that something that any Diablo tuner can do?

I got the Torque Management tune from Doug @ BamaChips and it made a major difference in the shift firmness!!

I wish Diablo Sport would just say their predator does or does not turn off the torque management. I don't understand why it is so hard to pen them down on this. If in fact they have made a statement please advise as I have missed it. Thanks
