Completely worth the asking amount. I have had the other name brand versions which cost a ton compared to this. My only complaint is the Eco mode isn’t as effective IMO as the others.In the end I would for sure but this same unit for all my vehicles without hesitation. I suggest recalibrating the unit right out of the box.

Revived order to find not fitting arfter trimming the plugs got it to work and very noticeable

Works as intended.. throttle response is much better now.. great product!

Great price easy install setting a noticeably different only thing is cords are a little cheap and always program it to vehicle before first start up

Caution, lengthy review. First, gets rid of throttle lag. That alone was worth it. Beware, there are a lot of negative reviews and I haven't had this very long. Now the details. In sport mode my 2018 Silverado is perky like a cable throttle and the frustrating downshifting when coming to a stop is gone. My mileage went from an average of 15 mpg to 17 mpg.In racing mode the throttle was snappy but pegged out at about 40% of the pedal. The truck lunges in forward and reverse and drives like a manual shift with a tight new clutch. I drove it quite a bit to get a good feel for it. It was fun to drive but got old quickly. I drove in town and a couple of road trips to towns an hour away... 35 minutes in this mode! Fun to use now and then but no practical use... Quick out of the hole but as you know, not any faster. Will not give you the ability to race! Observed for three hours of driving and get this, my mileage remained consistently at 8 mpg per the truck computer. That's correct, 8 mpg! Reflected at the pump. Economy mode is a lot smoother than it was without the 9 Drive and my mileage went to just under 20 (19.8 mpg). Tested this in town and two road trips around 4 hours each with interstate driving at 70 mph on one trip and 78 mph on the other using cruise control (which some feels hurts mileage.) I now use economy for travel and P2-3 for normal driving. I now have a truck with a "normal" throttle and a gas saving mode for trips. Well worth the money. I see many complaints about these failing after a brief period so... We will see. For guys like me who are searching for a balance of performance and economy for a daily driver I will include my choices. I did a lot of research on throttle controllers, tuners, exhaust configurations, and what will or will not void a warranty. I chose the 9 Drive, a cold air intake (Rough Country), and an OBD box to negate the "Active Fuel Management" system. My 2018 now performs like a truck should and the cash investment was very affordable. I replaced the stock muffler (and flapper valve) with a Thrush Cherry Bomb and added a shutoff valve. Now I open the exhaust at the tail of the Cherry Bomb and advance the 9 Drive and I have a truck that runs and sounds amazing. Then I set it back to P2-3 and shut the exhaust valve,(which sends the exhaust through the stock pipe and resonator), and I can take the wife out in my "stock" truck that is smooth and quiet. Best of both worlds. She grew up, I didn't. Hope this helps, especially you Silverado owners!
