I'm new to the tdi crowd. fuel prices forced me to park my duramax.I now have Jetta wagon for my estimate and service vehicle. I had Jeff Tune my 03 wagon(rc2) about a month ago. I wanted to encourage anyone thinking of having it done to DO IT.my 03 wagon had 208k on her when i brought her home. Cleaning the intake and egr made her driveable. Jeff made her fun!!I had a smile from ear to ear the WHOLE 2 hour ride home. MPH went up 2 points. With fuel prices what they are ,we can,t afford not to retune. If you're thinking of doing a rocketchip tune,DO IT!! You won't regret it .P.S. on the test drive,Jeff noticed my turbo was over boosting.He fixed the sticking actuator rod.Another week or two and I would've "lunched"the turbo.He saved my turbo. Just that alone was worth the trip and the cost of the tune. Hat's Off to Rocketchip Performance !!!!
