Have had my 17 ED since Dec '17. Love the truck. I'm still running stock. Like many I too have experience the turbo lag but have not ever had any life threatening experiences. Approx 17K of my 30K miles on the truck have been towing my 23' TT. So, question. What have others experienced, both positive and negative with the GDE Hot Tune? I'm looking for real experiences in MPG, Turbo Lag and Towing. I look forward to hearing your experiences.
