Cadillac Escalade, EXT and ESV Forum - 1999 - 2006 Discussion, Best Power Programmer for a 2000 Escalade in Cadillac Escalade Forums; I was wondering what the best power programmer for the 2000 escalade, or if it is even worth it. Thanks ...
I bought my '00 used in 2001. At that time there weren't that many programmers out there. On the F150 that I traded I had a Superchips programmer that made a world of difference on. But it mostly modified the shifts points of the tranny, allowing the engine to rev higher. As the Ford engine was an overhead cam, it developed it's hp at the higher revs. So the programmer helped that vehicle a lot. So I decided to try a Superchips on the Lade. Unfortunitly the instructions were basically for a Tahoe/CK vehicle and were not specific for the On-Star. Evidently I didn't get the installation correct & the theif protection disabled the vehicle. I had to have it towed to the dealer to be reprogrammed. So I gave up on the Superchips and returned it, less 20%.
I'm sure that the instructions are much better by now. However the shift points on the Lade are pretty good in my estimation. So for the programmer to be of benefit you have to go to 91 or higher octane gas and allow the programmer to advance the timing. I'm sure that this will give more hp & maybe better mpg. But I don't know how significant the improvement will be. On mine I have to run 89 octane to keep it from pinging, so the stock timing isn't lazy. The other benefits from the programmer may be of value, such as correcting the speedo for different tire sizes. I think that you can also adjust the firmness of the tranny shift points. Raising the top speed limit is an other benefit if that thrills you. If I was pulling a heavy trailer consistantly I would probably get a programmer to adjust how the tranny shifts.
I haven't seen any blazing testimonials about adding a programmer to stock '99/'00 Lades. There may be some out there, but I haven't seen them.
