Flashed stage 1 onto my 2011 mazdaspeed 3 and was getting around 12.3 pounds of boost, and decided to go back to Stage 0 and see what I was getting. I was getting around 14 pounds of boost and in 4th 15 pounds of boost. After chatting with some people in Shoutbox, I ran some logs to see if you guys can help me identify the issues! Thank you a ton. Logs pasted below

I trimmed the graph right before I WOT, that why you may see a flat then a spike!

man I have no idea what is going on with that stage 1 tune but it does not look right at all.

You said you have the cobb sf maf housing (pictured below, the part the maf screws into) and this map is for the sf intake, right?

The afr drops to mid 9's which is way too rich. The ltft is at ~16 during wot for some reason which doesn't seem right, the car is closing the throttle plate for some reason, nothing stands out as why. fuel pressure seems fine for stock internals and it isn't knocking. wgdc wasn't logged which is a bummer so I can't really see what it's doing there. If you have the cobb maf housing and the correct tune for it, this stage 1 tune should be working.

I would flash the stage 0 back. That log looks a lot better overall. It isn't closing the throttle, and the afr is much better. There is some KR, but it's not over 2.0 for very long. I can't tell if it's real or something rattling around. To my eyes it doesn't look like it decays like real knock would.

I can’t see all of those parameters mango? Is it cuz im on my phone instead of a desktop?
 
Stage 0 looks fine because it's essentially stock mazda tune. Stage 1 looks like garbage because it's a cobb lolcopterots map.

When I first got my accessport when I was a beardless child, I flashed stage 1 and it did nothing but hit fuel cut all day long. Garbage. Also you can assume your knock is probably real unless you can open those maps and look at the fueling. Stage 0 won't have any knock issues because it's pig rich.

Get yourself at least a flashtune from freek or dizzy until you save your pennies for a real tune. Not sure if PD or Nishan offer those but they might.

The stage 3 tune I was on would boost spike in the winter and was lean during wot. Not the greatest for sure lol
 
No wastegate duty cycle in the logs?
This is lower than the stock tune which will go up to load 1.65, that in the mid range meaning 14 so 16.5 PSI of boost depending on the altitude/baro and ambient temps.
