Time for a long overdue update. After spending an entire Saturday on the phone with Xman (great customer service btw) resetting all turbo adjustments and still overboosting, the turbo was finally declared bad out of the box. I sent a ton of logs to him trying to get the overboost under control while making small adjustments to the set screw at his guidance. He sent a new one and I was pretty shocked when I had the exact same results. He then spoke with Jeff and I was sent a new tune, and the overboost was gone. Which leads me to believe the tune was the issue the whole time.
I still was not happy with the drivability. It made no power under 2300 rpm. It had no off idle power which made city driving suck with the sb endurance clutch, and would be a smokey pig if I gave it much throttle until boost. So I ended up parking it in June as the support from the tuner was simply not there. Last month while reading through some Facebook groups, I found a guy named Nelson Martin who tunes tdi’s through his company Tekmektronics. I explained what was going on and ended up purchasing a tune from him.
The difference is absolutely night and day. The turbo spools much faster. No overboost or spiking. Off idle power feels similar to my Cummins. My car is now a pleasure to drive again. This is the third tune I’ve had on this car and I can tell you Nelson is the real deal. He’s the one to go to if you’re actually interested in making power, not just smoke. Also, he actually responds when you message him. I’m looking forward to seeing my mileage increase with his tune vs the old one as well. Tekmektronics got my car running awesome and if anyone else is having issue getting this turbo tuned (I know others are) Nelson is the man to talk to.
