Hey guys,

I just bought a Hypertech Power Programmer III off of Craigs list. I got a great deal on it and they said it had never been used. I'll let you know if I got taken or not after I try to do an installation.

Very cool, The one complaint I have with my truck is that in 95 is was not OBD II yet so I can't really take advantage of the OBD interface equipment. Keep us posted.

I installed it at lunch. It took about 10 minutes. I have only driven it around the block, so I can't tell a whole lot yet. It does seem to idle smoother and the shift is a tad firmer. It also raised my redline to 6,000 rpm's and set the speed limiter to 128 mph. I could have raised the shift points also, but I left those at stock for now.

Very cool. It was that easy to install huh? What other gains do you expect to get out of it?

It was a piece of cake to install. You just plug it into the data link connector under the dash, answer some yes/no questions and it does the rest. The biggest improvement will be the WOT performance. It changes the timing curve for a more aggressive timing. Only downside is that I will have to run the high octane gas until I decide to put it back to stock. If I know I will be doing any towing, I will add the adjustment for the shift points.

They sell for $350 or more. I got this one for $150. I was pleased to say the least.

That's a pretty good deal. I guess I don't know how they work. Can one programmer work for multiple vehicles, like if you owned 10 of the same truck (like a fleet) and wanted to program all of them.

Once you program the vehicle, you cannot use the programmer on another vehicle until it has been unloaded from the first vehicle. So it can be used on multiple vehicles, but only one can be programmed at any given time. It records the vin number in it's memory.

Don't forget that if you use one of these programmers on a vehicle still under warranty you must change the engine back to stock specs before taking the vehicle to the dealer for service or repairs otherwise your warranty will be voided when the dealer tech guys check your specs and find that everything has been changed.

HyperTech III

I have one of these units on my '01 K1500. I raised the shift points, raised the rev limit, changed the firmness, and went to the hi-octane fuel. I also run a K&N. Torque is about the same as stock, just a little smoother, but the WOT is a lot hotter. At interstate speeds I get about 20mpg. I have 106k on this 'Burb. I like using it to get the DTC codes since with this many miles and my off-roading, I tend to unplug wires. When I use the Tow/Haul mode, the unit really has some oomph.
