Very impressed with this chip. First and foremost, with the EPA crack downs, this chip comes with a sticker starting that is is CARB legal and it has the EO number. Secondly, it was very easy to install, instructions were easy to understand. The truck runs very smooth, it spools much much lower in the band. I can now reach 5 psi by 1300-1400 rpm and it climbs very quickly after that. I'm over 15 psi by 1600-1700 rpm. I've been running the 75hp setting. The boost maxed out at 17psi on the stock truck, it will reach 24 or 25 psi now. Climbing over our local mountain, I can now comfortably run 6th gear, whereas I had to downshift before or watch my egts climb upwards of 1100 degrees. Now I can hold 6th gear and my egts stay at 950. This tuner helps the engine run on boost rather than just over fueling it and it shows. Unless I'm hammering hard, my egts run 50 to 100 degrees less pretty consistently. I did a 0 to 75mph pull WOT and only hit about 1100 on egts. I'm incredibly impressed with this product and I love the high idle for warm ups in the morning. My only other mod on this truck is a 4" MBRP turbo back with no muffler. I even noticed my exhaust tone to be deeper and more robust because the engine pulls more air. Im very confident that if I can keep my foot out of the pedal, I will see better gas mileage because it takes nearly no pedal effort to make the truck move at normal driving situations. This is on a 99.5 F250 4WD with a zf6 trans. Shipping was quick and got to me in two days even though I was halfway across the country from their warehouse. Big thumbs up to both Edge, and riffraff. Excellent product, great website and service.

Nice product easy to install and with the 6 different tunes that can be burned on the chip it is very versatile this along with other mods has made my truck an absolute monster. This will put a smile on your face when you run it

What a difference it made in the 2000 F-350 that I installed this on. Easy to install and great power. I think this is a perfect chip for those wanting more power at a great price.

Installed easily and made a world of difference over the gold superchip I had installed. I picked up a couple of extra miles per gallon and my transmission and wastegate operate much smoother. And the increase HP its like a new truck. Big thanks to Clay for helping me.

Installation was simple and straightforward. I installed this with the Riffraff billet compressor wheel and the 6637 filter kit, plenum Y boot set and gage cluster (ISSPRO boost pressure, trans temp and EGT). Very happy with the results, truck power response is highly improved, turbo spool response is immediate. Truck runs like a different animal. Not sure about improvements in EGTs because I didn't have any baseline, but I assume they are better. The EGTs will pull into the red on grade, so it's nice to have the gage. Just downshift and reduce power to stay below 1250F and all's well. I just ordered the Diamond Eye 4" exhaust kit, that should help the EGTs even more. I only run the edge on setting #3, don't see any reason to use the additional power settings and haven't played around with those. Clay was a big help selecting parts and the orders were shipped immediately. Riffraff is a great performance parts company. Very happy overall with all the parts!
