Bought an MSD 7AL3 box from a member on here then after some researching read about the problems people were having. Also read about Tech West and them being able to repair and modify MSD ignition boxes. After talking with him on the phone and being very impressed with the knowledge he had and outgoing business practices I sent the box to him just to lessen the probability of ignition problems at the track later. He called back a few days later saying that he did a pre and post performance test and the box was in working condition but was not up to par before his modifications, now it's operating better than new. Very pleased with my experience from Tech West Racing.
