    Question about 08 Trailblazer ss e67ecu

    I have 2008 TB ss with a forged iron block 6.0 and lsa on top(2.4 PULLEY LSA CRAnk pulley). Im having an issue when getting into boost the timing drops to 0. Right around the 163kpa mark. Truck is on e85 has 1000cc injectors and warblo 450 fuel pump. Feels like it hits a wall when getting over 70% throttle. Ive attached the log if anyone could help.

    I doubt this will fix it but try changing Max Torque ECM 2869 back to stock.
