Hi, I am hoping someone can point me in the right direction to tune out the TGV valves on a 2001 JDM wrx, CAL ID: A4SD501A ECU ID: 1B04400405

I believe some models came without the TGV valves, so hoping that I can look at copying the tables needed from there in to my file

for that year just switch off the codes is sufficient, if you've added fancy TGVless housings that improve flow you might need a small adjustment to timing or boost control but most times it wouldn't be noticable.


make a log, see how it's running, or retune with Carberry is always a good shout.
