Anyone done the Stage 2 496HO ECU performance upgrade?
 
Whipple superchargers offers a 496HO ECU performance calibration:

Stage 2 $995
The Whipple stage 2 maximizes the power output of the stock engine by running 91 octane or better, increasing the maximum spark advance, increased ignition power from the individual coils, denser air charge from the low temp thermostat, maximized air-fuel ratio in each individual cylinder and increased air flow from the hi-flow filter. Calibration increases torque levels throughout the entire rpm curve while making more peak hp for increased speeds.
Key features:
• Hi-performance ECM calibration
• Low-temp thermostat
• Hi-flow K&N filter
• 5450 RPM limit
• 8% - 10% power increase over stock
• Increased plaining ability with increased torque output

This has been out approx a year now (I think) and I was curious.
Has anyone done this? Does it increase speed? Are you impressed with it and is it worth it??

I dont know how it performs but I guess it voids the warranty, huh?
