When I was looking for a quality, low price chip I knew the place to look was autoanything. I bought the Quadzilla Stealth II 135hp model chip and installed it on my 2001 LB7 Duramax. It was a HUGE difference, spool up is so much faster and the truck hauls! And when towing my boat the truck is a lot more responsive, you don't have to wait for the turbo to spool before you get power, it's already there! And a good sign is that you only blow a little smoke when the turbo isn't fully spooled which shows a good fuel to air ratio, meaning that the tuning is placed correctly. My EGT's are a little warmer but nowhere near anything dangerous. I re-calibrated my tire sizes and now my speedometer is dead on. The only thing that was a little annoying is whenever you want to adjust something you have to pull a few fuses, which gets redundant when you want to experiment with settings. Totally worth the money, you will have a blast with this product!

This is the second Stealth tuner I have bought for my diesel trucks. I bought the first one in 2005 and bought a Stealth tuner in 05 for it. It has worked great and saved me lots on fuel. I now have a Suburban with a duramax in it and needed a tuner so I went on AutoAnything and ordered a Hypertech tuner (Because local dealer recommended it) I then tuned my duramax with it and found that it de tuned the performance. I had less get up and go and the Pedal response was very slow. I called Hypertech and after discussing what I was getting from their tuner. They told me to return it. I did that and then bought the Stealth 2. I then tuned the duramax with it and now have the same GREAT Performance I have had with my old Duramax tuner from Stealth. I now have two Duramax engines and both are tuned with Stealth. Hope this helps others. Toby P - Cave Creek, Arizona.

I have a '99 GMC Suburban 4x4 w/350 & 3:42 gears getting 18 mpg on the Hwy - babied! I wanted to beef up the towing a bit but didn't want to shell out $2k to do all the gear changes, so i spent $300 for the Stealth 2. Had it installed in the Power Mode. The first "babied" trip I got 20 mpg. Today I'll install it in the "Economy" mode and hope for 30! The "Power" mode seems to be the one I'll keep it in though...just gotta see if what the MPG's are in the other. I'm Happy!

I have only used the "Economy" mode so far. In the first two tanks of fuel I have noticed a slight improvement in overall mileage. I'm up from about 18 highway to about 19.6 or so. And overall from about 16.5 to close to 18. I haven't used the power mode for towing my trailer. I'll have that chance in May.

I saw results after the first install of the Stealth 2 programmer. Took a trip and averaged 3 to 4 miles to the gallon going, however during the trip I put duels on my pick-up and the milage on the way back was not as good, due to a heavy foot every chance I got. Thank you and with a little more tuning, I think my 6.0 will run better and get better fuel milage. I also added the Airaid cold air box as well as the throttle body spacer. Hell of a choice. Highly recommended.

I'm very happy with my product. I was a little hesitant about ordering it because of the cost but I'm very happy I did because I can definetly tell I'm getting those 30 extra horses! My Blazer now has over 400hp with everything else that I have installed. Thanks AA.

I have an '06 Duramax 6.6 and had been giving serious thought to purchasing another Quadzilla Diesel Programmer since I had very good results from one I had for my '03 Duramax. When fuel costs soared, I purchased a Stealth 2. I was looking to reap some benefit on fuel consumption. I programmed in the lowest power increment at 50hp. I noticed immediate results. The truck was more responsive in acceleration, and I noticed a 3 to almost 4 mpg increase. Every bit helps! Very good product.
