Ask the dealer to data log all of the engine sensor outputs while the car is running. Paying close attention to the crank and cam position sensor output wave form. Does the car rev fine without a load? Another simple thing to have them check is the TPS sensor.
None of the email tunes are going to be 100% optimized for your vehicle. If you really want to have the best tune for you car then it is wise to have a custom tune done on a dyno. My prefrence is load based dyno.

700rwhp is not going to happen NA on pump gas easily, possibly at all. You'll need the largest ci bottom end with Striker Race heads with further portwork and a custom intake. The cam will have to have a lot of overlap. So much so that it would make the car no fun to drive on the street. I think...
You can talk to the person who programmed the SCT to add some decell enleanment to get rid of the popping on decel. Lots can be done with the SCT. Talk to any of the forum vendors that work with the SCT to get all of your questions answered.

You can do 99.9% of what the VEC can do with the SCT without adding extra hardware. If you want to do the tuning yourself, then you can buy the pro racer package.

I'm sure the VEC is quite simple as it is only a piggy back. I could get the software and look it over. If you could find a load bearing dyno around you I could work with you via email or over the phone to get your car dialed in.
Give me a call if you want to chat about the options.

I've only tuned a handfull of gen 3 vipers with the SCT. I just recently became an SCT rep. Before that I used the AEM on viper projects. I've not used the VEC2/3.
I'm looking for someone in the South Florida area with a stock or near stock gen 2 viper to build a SCT tune. The person who's car I use will get a STEEP discount for the use of their car.
I already have a nice program for the Gen3 viper. You can see the results on my website BritoSpeed - Need...
It does not need to be in 4th gear on a mustang dyno. Any brand of load bearing dyno can use any gear and get the same results. Only inertia dynos need you to run in a 1 to 1 ratio. Use SAE or get both corrected and uncorrected numbers. Ask when the last time that they calibrated there load cell...
