Just had to share this with the rest of you. I have been having problems with my boost bleeding off on my 1999. Went to Cummins and had the map/boost sensor replaced and the problem was still there but not as bad. Was thinking it was the waste gate and was going to disable it but heard that over boost is a bad thing. So I pulled my PowerMax 2 from TST out from under the dash and started looking at it while I was driving and noticed the boost light would sometimes go out or get dim so I turned off the box and the bleed off quit. Called TST and got in touch with Greg and he helped me out with my problem. It came out to be dirty conections on the map sensor and the injection pump.
I just wanted everyone to know what good people work at TST and how nice and helpful they all are from the women that talk to you when ordering to the guys that help with tech. questions. This is a great place to do buisness and I will keep doing buisness with them for all my proformance needs on my truck. (sorry so long but thought you all should know)
Great company Mark Chaple.
