Just wanted to share my experience with Steve. He set me up with an autocal and DSP5 tuning for my LBZ. It was my first time messing with EFI live so I was basically clueless. Steve spent over an hour explaining everything to me and answered all of my novice questions before I even told him that I was planning on buying. He has been extremely fast to reply to any email, text, call, or pm. He even answered some questions I had late last night when hooking my DSP5 switch up. The truck runs great and I'm very happy with everything he has done. I know there are many good tuners on here, but I would highly recommend Steve as a tuner and for outstanding customer service. :thumb::woott:
