I seem to have fixed my trans problem. There is a throttle position sensor for the trans that you can adjust, and, for whatever, reason, it stopped having problems when I put it back to stock position.
Marc: Appreciate the insight-Iam definitely waiting anxiously for Hypertech to come out with a programmer. I truly believe that they could wake up this truck. Hennessey told me that their first mission was to get a better torque converter. This, no doubt, would make a huge difference, but I'm sure it would void the warranty.
As far as de-tuning...This truck seems to change its mannerisms on a daily basis. I am sure the computer makes constant adjustments. It chirped like crazy through the gears when brand new. Now, it only does it on rare occassion (1,200 miles). Also, as someone else noted a while ago, there are 2 re-programming stickers on my PCM...
Lastly, they MUST have de-tuned it somehow, as I don't think the drivetrain, from the TC back, could handle the full force of 500 HP. I agree with Hennessey that the TC is likely the biggest culprit. Look at the split drive shaft and the rear-end and axles. My guess is that the QC would be damn lucky to lay down 410 ponies to the rear wheels. If it did, I would guarantee that it was only because the TC was locked and the PCM gave full power at WOT and high RPM. The engine management program, I'm betting, delivers much lower power up to that point. I've had cars ranging from 180 to 633 flywheel HP, and this one sure don't feel quite like 500. If it delivered max power throughout the RPM range and gears, with the heavyweight that we are dealing with, it would likely blow the axles off the truck. Just my $.02.
