Maybe a dumb question, please delete if it's been covered, but I'm wondering if my '03 JSW already has a tune?
I'm 3d owner, friend just gave it to me because it needed bunch of things, didn't tell me much, just handed me 17 years worth of service records...
Going through the car I found KII USB dongle, he didn't know what it was, just left it in there for me to find. I already installed software and it works fine.
He has no idea what was done to the car other than dealer service receipts... Makes me wonder if this thing has a tune? First owner was a VW fanatic...
When I first got it seemed very slow, but after I replaced filters and cleaned the EGR it got little better, but then on the next trip it went in to a limp mode, then it was fine next day. I've taken few long drives (30-45 minutes) and it seems to have gradually improved performance, no more limp mode, pretty good acceleration above 3,000 rpm, seat of the pants it feels more than 90hp, not quite as fast as my other car but definitely not slow. If it has a tune I wouldn't know it because I have no idea what stock ALH feels like, never had a diesel in my life (life long Honda Fanboy) and only a couple Turbo cars, both Volvo.
