Here’s the next progression in the series of maps I’ve ran while having my ECU tuned for my little big turbo.
From the last map to this one, I picked up a lot of power earlier in the RPM range. I was starting to get worried between maps that I had a boost leak going on. This one helped reassure me that I didn’t fuck anything up in the build and it’s still good.
I’m up to 21 psi now which is what the stock k04 turbo pushed. The 18g I installed is capable of around 23-24 psi as it sits in my car now. I’ve still probably got another 4 or so maps to go through, and if I keep seeing similar performance from map to map this thing’s gonna be a monster. There’s still a ton of room to grow where it flat lines at 5000 rpm.
As always, it’s important to note that the logs used to create the dyno data are pretty unreliable as far as real world numbers. It’s just as close of a visual representation of what’s going on as I can get without buying dyno time.
