Again, the only reason I posted in here was because I was asked. Mods can move the post above to a new thread if they like. I don't want to make it seem like I'm trying to derail this thread but when I am asked to voice the benefits of one of our products I will certainly do so.

Mods can let me know if I'm wrong here...

The one difference I noticed (and didnt like), The IPCM changes shift points by changing the revolutions on the OSS (may want to recheck my file, as I may be calling it the wrong thing). But DHP changes all the CORRECT settings to change shift points.

*note this is on an older (but after timing issue) IPCM.

I have a 97 IPCM standar bin file, and DHP V 1.5 to compare. Just stating this as these are BOTH MY pcms!

Other than that the IPCM(standard) isnt to far from stock, mainly just skip shifts. But the DHP V1 offers improved fuel and........But as Rogue stated you can have MANY other thing ala carte

I don't recall what my I-PCM did at 40mph.

With the DHP, it will do a skip shift to 1st gear from 3rd. It'* pretty hard on everything, but your car will take off hard at 40mph. It'* right toward the top of 1st gear.

Unless I am missing something, It doesnt look like the DHP PCM is available for the bonneville, but I might be missing something it is early in the morning.

Their website is really outdated. They can do Bonnies.
