I’ve had it in my truck for approximately 9000 miles already, gone through 2 dealer (free) oil changes, removed it both times, no issues from dealer, and could not wait to re install it after, certainly makes a significant improvement. Got it down to about a 15/20 minute install/removal.
I was also between the diesel
Gladiator and diesel 1500 gmc at4 and am soo happy I went with the gladiator, test drove both multiple times and ended up going with the gladiator, would not change my decision.
So I installed mine last night and all I can say is it truly does give more power then in stock, very noticeable difference and I am very pleased with my purchase. Now thinking of adding in the pedal monster as well
The day I took delivery is the first pic, and the wheels went on the second day.
