I finally got my car running. 1992 Turbo'ed teg. I am running a 14b DSM turbo, with 320cc injectors, and a Vortec FMU for more fuel obviously. Now, I can run 2-3psi all day with half-throttle short shifting. Once I really beat on it and actually run my full 7-8psi that it's set at...my car goes into a "retard mode I guess". It will spit and sputter, until I restart the car... to reset it. I have tried a check valve off of the map sensor but doesnt work...please help. I wanna see the cars full potential. Any comments will help, thanks.
