I had the tune with the downpipes and intake done back in April 2022, however with the recent mods, done in August, I have noticed that it still activates Transmission Malfunction under the same amount of throttle. I was thinking it may be due to the fuel pump and with the recent amount of gains, it may be running lean. Would you say a HPFP would help the reliability under hard throttle?
