L99 Dyno tune results!
Today my car was dyno tuned by our sponsor Modern Muscle! 
Here's the results!
Picked up 12hp and 26ft-lbs at peak, but as you can see by the dyno graph, there is a huge gain in both horsepower and torque throughout the RPM range.
The gain is near 30hp and 30ft-lbs in most areas!
(the difference in the dyno numbers vs my other stock dyno is just because of the difference in dynos)
Boy did this car wake up A TON with just the tune!
I highly recommend a tune, it's an amazing improvement!
The power increase is very noticeable, the shifts are firmer and faster, and the shift points are definitely better.
Overall I'm VERY pleased with the results!
I'm anxious to get back to the dragstrip and see how much faster it is!
That should happen fairly soon!
STAY TUNED for pictures and videos!

Very nice gains, Tim! Do you know what they actually changed (other than tweaking spark & fuel on the dyno?)

Looks great Tim!
What changes were made to Torque Management on your car?

We change fuel and spark obviously at WOT. IAT timing pull tables are modified to reduce IAT heat soak timing pull. This table is overly conservative on these Camaros, worst I have seen yet. This is not a PE tune, for those of you who know what I mean. Commanded and actual AFR is equal to each other. The MAF transfer function is modified to make Lambda equal 1. The power enrichment switch point is modified, enrichment rate is dialed in and PE delays are modified so that the WOT hit is much more crisp and responsive than stock. Timing is tuned to MBT ( max brake torque) throughout the rpm range. Engine torque management is removed so that the pedal position will equal the throttle position. Burst knock retard is managed better, again to greatly improve throttle response. Speed limiters are raised.
Transmission wise, there are a number of things going on there, but one of them is reducing transmission torque management, managing shift points and the dynamics of the actual shift. The new control system that goes with the A6 is wonderful and very tunable. Just ask anyone who has an A6 tune from modern muscle, it is an amazing new transmission. I personally own a G8 w/ the A6 and the thing shifts like an F1 car.
There are a number of other details that are dealt with by us, but this is a good glimpse into what we are doing with a tune. Modified cars obviously bring with them, many more things that we manage, tune, and change.

Agreed!
Like AJ said, the guys at Modern Muscle really really know their stuff.
On top of that, they're a cool and fun bunch to hang around with!
One of many photos taken during the photo shoot:
MANY more to come.

That custom paint job we put on the front of the building turned out nice for the photo shoot, LOL.
