I'm running a ct26 turbo on my 1j with the stock ct26 wastegate. I have a greddy boost controller spec profec b. I've been running this setup for three years never had a problem until now. The boost controller is set and tuned at 21lbs. Now only in first gear i'm getting 8-10lbs all the other gears are normal boost 21lbs. Any ideas? I'm thinking my wastegate is fine because if it was a wastegate issue i'd see the same boost drop in all gears. Could it be my boost controller solenoid or maybe the unit as a whole? Any help is appreciated.
