I agree to what you say. I took a gamble. Rajiv is not from bangalore, he came on request to bangalore, tuned my car and drove to Pune. So far, 50k plus kms no issues, also considering I do 8-10k kms per month only during nights. I gained a lot of confidence If I run into problems with the tuning, I believe the MJD will go to limp mode and still be driveable.
