I recently decided to go Stage 1 with my car and began shopping tuners. Everyone recommended going custom over OTS and I have to agree that is true. I used the OTS Cobb Stage 1 for 93 and while the car pulled harder it wasn't very smooth, only coming on the power suddenly and then dying out. I got in contact with Brian and the first version he sent me was already better than the Cobb one. It only took three versions before everything was good and now the car pulls harder and is very smooth, easier to drive than with the Cobb tune. Brian was very patient. He answered a bunch of questions I had before I even bought anything. After I purchased the tune he was quick to respond and it only took about a week to get everything dialed in. I recommend JST to anyone looking for a custom tune.
