Dave,
I have a Dr. Performance Stage III, 110 HP, and I am very pleased with it so far. Granted, I haven't put a ton of miles on it yet, but so far so good. There are a lot of guys here who are not Dr. P fans, but I had an Edge Comp on my 2nd Gen and really had to watch the EGT's. With my Dr. P. I've touched a tad over 1300 a couple of times pulling a steep grade at WOT, but for the most part it seems to run a lot cooler than the Edge I had. Boost pressures would also exceed 35 lbs with the Edge, tough on a stock turbo, the Stage III gives me just under 30 lbs. Also, with the Edge my MPG barely benefited at the lower settings, and at settings 3-5 it would suck fuel like a big block gas motor! MPG with this module so far has been remarkable, I've got as high as 22 MPG on the highway, and 19 combination city/highway. It comes on strongest with your boost, once I hit 1900 RPM and 20 lbs of boost it's like pushing a nitrous button. A lotta fun! If your interested, call Jeff @ Advance Diesel Specialists
http://www.advanceddieselspecialist.com/ , he sells more than one brand of box and will go over any questions you have.
He is a great guy to deal with and has competitive prices, so I don't think you'll be sorry.
After I installed it in my truck, I pulled it out to let my DC mechanic try it in his, he ordered one the next day. This is only my personal experience, so hopefully it helps you.
Mike
