Wait, I don’t remember seeing the increase in top speed anywhere on the TDI website or the instructions that came with the tune (installing mine this week). I know we are limited to 99 mph and to be honest in this big beasts that is plenty and probably won’t ever see that number. However, I really didn’t know about the raising of the top end speed. Where did you read/hear that if you recall? Btw, I bought the TDI tune to give a little more power as I have really weighed my blue one down with all the gear/accessories, especially the SPP undercarriage plate protection kit (heavy as hell)!! Anyway, if I want to go fast, I just jump into this bad boy…….IYNYKI admire your spirit, but that's not going to happen.
I am not even tempted. I spent every day of my life between 14 and 48 looking for more horsepower and torque. TDI tells us we get another 10 mph out of this brick at top speed, so 110? I'm good.
Btw I saw a 16.2% increase in fuel economy in my initial default run on the tuner at level 4. Slow is smooth, smooth is fast (or in this case efficient).
Edit: well damn if I didn’t just go back on the site and click a few more links and found it!! Never even saw that before I purchased. Interesting…..again these big lovable tanks aren’t meant for speed but it’s nice to have a little more power if needed for towing, if like me you have weighed it down with more weight, etc.
