I ordered everything i needed to Make my Duramax a powerhouse. Thier efi live autocal was great. I did have to pay $40 tariff fee on that because it came from Canada but im sure there is a way to get that back. The 4 inch exhaust, down pipe, up pipes, hot side pipe, egr delete and reroute alomg with the new cold air intake perform excellent and they give my truck the power and sound I was looking for. I look forward to working with SPELAB for future builds. I hope they get transmission tunes in the future and decals because I would love to advertise where I got my performance parts on the truck. Also, a sponsorship program for serious builders would be great along with lighting and wheels/tires. I had to shop around during this build but would have preferred to do a one stop shop at SPELAB
