Been a while since I updated this thread. Got rid of the Haltech E11v2 and switched to an AEM Infinity. Found lots of hidden ponies and torque with the new computer...it would appear that the Haltech was not up to the task of controlling a LS3. Recently moved to Florida and tuned the car for 93 octane.
Next upgrades are getting the traction & launch control functional and installing a 100 shot of nitrous that I've been sitting on for a few months. Hoping I can get upper 600s on race gas.
