If I were to install the Cobb FPR kit on my 2019 Subaru STI would I just zero out the Load Compensation tables in Access Tuner? No matter what I do with my MAF scaling the trims are still way off in the 2400-2800 RPM range and I am looking for the fix. The FPR kit seems to be the fix but would like to know how to adjust for this fix in Access Tuner. Thanks in advance.

If you have access to the Practical Reflash Course on here, Andre explains pretty well the tuning approach regarding the Subaru fuel system issues in the worked example!

But yeah, I think you should zero out the load compensation tables if you have an aftermarket fuel system that fix the OEM system issue. It's worth a try for sure!

Thanks, I'm going through that course now. I thought that Andre had mentioned zeroing out the tables, but I just wanted to make sure that was what he was saying. I didn't want to assume this is what was meant and mess something up.
