You have 3 knock counts. It's not terrible but it's also not great. You can decide if you want to turn it up or not.
You have the ability to log, so you should always log instead of just what people tell ya. Fuel is different all over, car mods are different etc. Log it, analyze it.
Try getting gas elsewhere once you've emptied the tank. It's fine as is but it should be clean on map 1 with 93. If it doesn't get better after trying a couple other pumps, I'd leave it alone and assume the gas in your area is poor. Map 1 should basically be cleaner than that on 91 and spotless on 93.

Got some “dumb” questions. Just got a JB4 hooked up on my golf. I’m running it on map 0 just to get some baseline data at first. When should I see max boost? Like I did just a quick drive with maybe one pull at a light and the data says max ecu boost was 2.0psi and actually was following that pretty closely? When do engines make the most boost? That seems so low to me, not sure what’s going on
You should be hitting something like 11 or 12 PSI. I haven't actually measured map 0 but should be around that. Stock, they make reasonably linear boost, likely pretty flat between 3k and 4500.
Highest boost I’m seeing is like 7-8 psi. Here is a screen shot. It seems actual boost is following ecu boost, which means I don’t have a boost leak? It’s a 5 speed running 87. Any thoughts? I feel like it’s low.

Isn't map 0 just pass through so stock?
Yep! Trying to figure out if at stock I’m low on boost cause the numbers seem too low.
Datazap and make a run at full throttle in 3rd from under 2k to 6500. https://datazap.me

Couldn’t get all the way to 6500 cause that’s like over 100mph and I don’t live close enough to Mexico lol. But here are some pulls up to 5500ish RPMs. Once again this 87 fuel on a 5 speed. Trying to get baseline boost, which appears to be max 10 psi for 5500rpm WOT
Unless you get better gas, You're already topped out. Any add would be limited by timing corrections and be negligible. You don't want to see ign 2,3 and 4 showing much higher #s than they already are, even after adding boost and less pings would be better.
What do you mean by less pings? I’m def going to get better gas. My plan was to get some baseline 87 data, baseline 93 data, and then map 1 93 data.

Less knock.
