I'm also interested in that. Last night I bumped my settings to 92% and drove 25 miles following the adaptaton instructions posted elsewhere by Eugen. I logged a lot less boost than I had previously at 90%. So I upped the settings to 94% and drove 60 miles to and from work, looking about the same boost on 3-4th gear pulls. I just upped them to 96% and drove another 60 miles doing some pulls but didn't log. I am disconnecting the battery for one hour between changes in the map.

I'm going to go out in a bit and see what the numbers look like. If they're not up around 13.7-14.0 like mine were at 90% I'm not sure whether I should put them back to 90% or leave them at 96% and drive it some more. I'm running the 12-19 map because I have no issues, and about 95-96 octane. No other mods (except a boost gauge LOL!!!).

So I am definitely curious how fast people have seen changes (if any) in boost levels (up or down) when they switch maps and the ECU starts to adapt...

So I take it you don't miss the v2.0.1 beta anymore?
Kinda knew you wouldn't once the v2.0.2 was dialed in for you.
My car is running really strong right now too.

Man your car boosts high.
You were boosting like 15.6 psi when you were on v2.0.1 with the ITG filter too huh? I don't think the filters make any real difference anyway, but I've always hated foam filters.
Are you a bit worried running over 15 psi boost on 91 octane though?

Please share your experiance. Thanks bro

Don't look at just the peak boost.
Look at the whole 3rd gear run.

I too actually got a bit higher peak boost at 92% than I did at 94%.
I also got just as high peak boost on 87.7% as I did on 93%

However, if you look at the rpm range when I tested 87.7% the boost peaked very quickly but held it for only a split second and then started dropping fast. Even though I got the same peak boost at 87.7% as I did at 93%, when on 93% it held the peak boost a bit longer and didn't drop off nearly as fast.
By 6500 rpms, I was nearly 2 psi higher boost on 93% than I was when at 87.7%.
It's like looking at a dyno graph, you NEED to look at the entire run, not just the peak numbers.
I'd take a dyno run that has 10 rwhp more from 3000-5000 rpms and from 6000-7000 rpms, than one that peaked was lower in those ranges but peaked 5 rwhp more at 5500 rpms for a brief second.

The map I really loved was the 2.0.2 beta. This map doesn't have quite as much torque down low, but pulls like mad up top. I get 15.4 psi on 90% as well. On the beta map, I'd see spikes of 16-17 psi when "conditions allowed" aka overboost. Sherwin consistently dyno'd 30whp more with this map over the 2.0.2 production.
