Ed Wright Programming PCM or Hypertech - Is there a comparison?
Just curious. I've got the Hypertech on my LT4. If I switch to the Ed Wright will I see a noticeable performance increase? Thanks all.

Any of the pre-programmed chips are just guesses. Even a custom chip from Ed is just a guess unless he actually gets some feedback and go back and forth a few times. The best would be to have Ed dyno tune it.

Another option is to do it yourself. http://www.carputing.com has the setup for tuning OBDII LT1's.

Both Ed Wright and Hypertech should have a good setup for stock LT1 and LT4.
I got mine done by him for the 383 and then started doing my own programming. You have the flash memory version so you can do yours without a chip but the software is $500 for LT1_Edit since you have the 96 ECM. You also need a laptop or move your pc next to your car.
I can give an idea of what he did on mine:
1. Added more spark advance when the throttle plates are closed (like at idle).
2. Raised idle to 850 for my cam.
3. Added 3 deg spark adv at WOT. He also added some advance at points below idle which made no sense to me. I have reset a lot of those values.
4. Disable CAGS
5. Disable some emission diagnostic stuff that I reneabled.
6. Modified the speed density table which I have left alone but don't affect my car since its got MAF.
7. Changed the fan temps
8. Reduced spark retard to 0 at lower load levels. I reset those.
9. Adjusted air to fuel ratio at WOT. I made some adjustments here as well. He reduced the air to fuel ratio a lot above 5600 which made no sense to me.
I have had trouble getting the free version of diacom to work with his programming. Not sure why though. I get checksum errors.
I have also heard some tuners move the data around in memory. I would not use their stuff because you'd never be able to mod it later.

On #9, the theory goes that after you are past the peak on the torque curve less fuel is required.

$2500 is for the non-VIN locked version. Its $550 for a version VIN locked to your car.

Can't the control module just be removed from the car and reprogrammed on a work bench or desk? That is the way Ed Wright has to do it when you remove and return the ECM to him.
