I'm thinking of chipping my '03 Passat 1.8T. Since I live in New England, I've found a place in Concord NH, TJM Motorsport that can do the chipping while I wait. They use Dahlback racing components and for $800 they can get the hp to 195hp. They also suggested I change the blow-off valve for another $160.
Has anyone had any experience with TJM Motorsport or Dahlback, and do you think I need to change the blow-off valve, or should I leave the stock one (made by Bosch)
The big thing for me is that they can do the work, while I wait - I don't have to mail the ECU to the west coast and have the car be un-drivable for a week or so...
